A rectangle has sides of length 3m and (x + 4) m.
Find the value of x, if the area of the rectangle is 18m²??
A rectangle with an area of x2 – 4x – 12 square units is represented by the model. An algebra tile configuration. In the Product spot are 21 tiles in 3 rows. 1 tile is labeled x squared. In the same row are 6 tiles labeled negative 6. Below x squared are 2 tiles labeled x, and to the right of the x tiles are 12 tiles labeled negative. What side lengths should be used to model the rectangle? (x 2) and (x – 6) (x 6) and (x – 2) (x 2) and (x – 10) (x 10) and (x – 2).

Answer:
In total, Esme will need to purchase at minimum TWELVE (12) pieces of fence in order to encompass her entire rectangular garden.
Step-by-step explanation:
Let us start off by isolating each of the two different length sides, and figure out which fence pieces can be used to it off.
For the three meter (3 m) side, we could utilize the following THREE (3) pieces...
ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 0.6 m length fenceAdding up those pieces provides us with our desired garden side length...
(1 × 1.8 m) + (2 × 0.6 m) = 3.0 m!
For the six meter (6 m) side, we could utilize the following THREE (3) pieces...
ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 2.1 m length fenceAdding up those pieces provides us with our desired garden side length...
(1 × 1.8 m) + (2 × 2.1 m) = 6.0 m!
We ought to not forget about the opposite sides of the aforementioned, to make up the four sides of the rectangle! In short, we double the number of pieces that we currently have...
In the end, the smallest number of pieces of fence that Esme will need to buy is TWELVE (12), consisting of the following pieces:
TWO (2) pieces of 0.6 m length fence TWO (2) pieces of 1.8 m length fenceTWO (2) pieces of 2.1 m length fenceI hope this helps! :)

a shop sells large and small oranges . a girl buys L large oranges ams S samll oranges. she buys al least three but fewer than nine large oranges. she also buys fewer than six small oranges. the maximum number of oranges needs to buy is 10
Answer:
Number of large oranges: x
Number of small oranges: y
y < 6
x + y <= 10
Hope it helps!!!!!!brainliest pls!!!!!!!!The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).
Let's represent the number of large oranges as "L" and the number of small oranges as "S."
From the given information, we have the following conditions:
At least three but fewer than nine large oranges: 3 ≤ L < 9
Fewer than six small oranges: S < 6
The maximum number of oranges she needs to buy is 10: L + S ≤ 10
Now, let's consider the possible combinations of L and S that satisfy these conditions:
L = 3, S = 0 (Total oranges = 3)
L = 4, S = 0 (Total oranges = 4)
L = 5, S = 0 (Total oranges = 5)
L = 6, S = 0 (Total oranges = 6)
L = 7, S = 0 (Total oranges = 7)
L = 8, S = 0 (Total oranges = 8)
L = 3, S = 1 (Total oranges = 4)
L = 4, S = 1 (Total oranges = 5)
L = 5, S = 1 (Total oranges = 6)
L = 3, S = 2 (Total oranges = 5)
L = 4, S = 2 (Total oranges = 6)
L = 3, S = 3 (Total oranges = 6)
As you can see, these are all the possible combinations of L and S that satisfy the given conditions. The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).

One rectangle is "framed" within another. Find the area of the shaded region if the
"frame" is 2 units wide.
10
7
The area of the shaded rectangle is 18 square units.
How to get the area of the shaded region?
The shaded region is the framed rectangle, and the white part is the frame.
We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:
width = 7 unitslength = 10 unitsNow, if we remove the frame, we will remove 2*2 units = 4 units for each measure (because for each measure we have the frame in both sides).
So the measures for the shaded rectangle are:
width = 7 units - 4 units = 3 unitslength = 10 units - 4 units = 6 units.And the area of a rectangle is given by the product between the width and length, then we have:
A = (3 units)*(6 units) = 18 square units.

Addison can eliminate $25 from Food/Clothes and $22 from Entertainment. D. The minimum payment is enough to pay off the balance within 24 months.
Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.
It is given that
Addison has a balance of $3,450 on her credit card.
APR = 18%
Current monthly payment = $86.25
She wants to choose a monthly payment for 24 months.
So for 24 months,
A revised monthly payment using the formula,
[tex]M = \frac{P.\frac{R}{12}. (1+\frac{R}{12} )^N }{(1+\frac{R}{12})N -1}[/tex]
R = 0.18
P = 3450
N = 24
Revised montly payment M = $172.24
Current monthly payment = $86.25
Difference = $86
So, she needs to cut the expenses by $86
If she cut $45 from Food/Clothes and $41 from Entertainment, she can easily pay the revised monthly payment.
Therefore, Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

which number is divisible by 5? 83 45 94 99
Answer:
45
Step-by-step explanation:
9x5
=45
Answer:
45
Step-by-step explanation:
To be divisible by five, the number must end with a zero or a five, and forty-five is the only number that meets these conditions. Technically, all the numbers are divisible by five, but 83, 94, and 99 divided by five would equal a whole number with a decimal, meaning the only option that equals a whole number is forty-five (45).

The third angle measures 30°. Two sides have the same length. The third angle measures 75°. The third angle measures 90°. All sides have different lengths.
Answer:
A. The third angle measures 30*
B. Two sides have the same length
The statement first “The third angle measures 30°” and statement second “Two sides have the same length.” are correct.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have:
Triangle with angle measures of 30° and 120°
Third angle measure = 180–30 – 120 = 30 degree
Two angles measures are same, and two sides have the same length.
Thus, the statement first “The third angle measures 30°” and statement second “Two sides have the same length.” are correct.

Marcus is buying a plane ticket. If he purchases his ticket on the day of his departure, it will cost $239. The ticket costs less if he buys it earlier. If he purchases it 20 days before his departure, it will cost $189. Model this situation by using a linear function. Then determine the cost of the ticket if Marcus buys it 3 days before his departure.
The modelled situation in a linear format is y = [tex]-\frac{5}{2}x+239[/tex]
The cost of the ticket if Marcus buys it 3 days before his departure is $231.5
Linear equationy = mx + b
where
m = slope
b = y-intercept
b = 239
Therefore, let's model the situation to a linear equation.
y = mx + 239
using (20, 189)
189 = 20m + 239
189 - 239 = 20m
-50 = 20m
m = [tex]-\frac{5}{2}[/tex]
Therefore,
y = [tex]-\frac{5}{2}x +239[/tex]
where
x = The day before departure
y = cost of ticket
To determine the cost of the ticket if Marcus buys it 3 days before his departure.
y = [tex]-\frac{5}{2}(3)+239[/tex]
y = -7.5 + 239
y = $231.5
