Answer:
A = 0.5(2x+6)(6x+13) = 6x² + 49x + 78Step-by-step explanation:
H = 2x+6 - the hight
3H = 3(2x+6) - triple the hight
3H-5 = 3(2x+6) - 5 - five less than triple the height
Area of triangle: A = 0.5BH
B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13
H = 2x+6
So:
A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78
A = 6x² + 49x + 78

Talia has a square framed moving box with an area of 16 square feet. The cube shaped box has a volume of 66 cubic feet. Will the poster lie flat in the box?
Answer:
4,4,64,larger,larger,would
Step-by-step explanation:
Begin by finding the dimensions of the poster. Since it is in the shape of a square, each edge will be the same length. and 16 divided by 4 is 4 and then you do 16 x 4 you get 64 and then you know is the box larger or not in this case the box is larger.
Which two binomials in part A didn't have an equivalent factored form? What made these expressions different from the
three that you could factor?
The two that didn’t have equivalent factored forms were x^2+16 and 16x^2+9
Answer:
The binomials 16x2 + 9 and x2 + 16 didn’t have an equivalent factored form. Both are sums of perfect squares instead of differences.

What is the slope for y=3x-4? What is the y-intercept for y=3x-4?
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question the equation of the line is
y = 3x - 4
Comparing with the general equation above
The slope /m = 3
The y intercept / c = - 4
Hope this helps you

I went to Half Priced Books and purchased 15 books. I paid $2 each for some and $3 each for the rest of the books. How many $2 books did I buy if I spent $34?
Answer:
Thus the number of books at $2 is 9 books.
Step-by-step explanation:
The number of the book purchased = 15 books
Total amount spend to buy the books = $34
The prices of books are $2 and $3.
Let the number of books purchased at price $2 = x
Let the number of books purchased at price $3 = y
Now we have to find the number of books that is bought at $2.
Below are the equations.
x + y = 15
2x + 3y = 34
Now solve for the x,
x + y = 15
y = 15 – x
Now insert it in the 2x + 3y = 34
2x + 3(15-x) = 34
2x + 45 – 3x = 34
-x = 34 – 45
x = 9
Thus the number of books at $2 is 9 books.

What is plane?In geometry, a plane is a flat surface that extends into infinity. It is also known as a two-dimensional surface. A plane has zero thickness, zero curvature, infinite width, and infinite length. It is actually difficult to imagine a plane in real life; all the flat surfaces of a cube or cuboid, flat surface of paper are all real examples of a geometric plane. We can see an example of a plane in which the position of any given point on the plane is determined using an ordered pair of numbers or coordinates. The coordinates show the correct location of the points on the plane.
As, per the figure we can say that the upper plane is made of plane ABCD.
So, among all the option BCD will be correct because BCD is part of ABCD.

Assume the Ziders continue to grow in the same pattern. How old would a Zider be that had 73 hairs?
Number of hairs in day 1 , a = 5.
Every day number of hairs increases by , d = 4.
So, it is an Arithmetic Progression with first term a = 5 and common difference d = 4.
So, number of hair in nth days is given by :
[tex]a_n=a+(n-1)d\\\\a_n=5+(n-1)4[/tex]
Let, after x days number of hairs are 73.
[tex]73=5+(x-1)4\\\\x-1=\dfrac{73-5}{4}\\\\x=18\ days[/tex]
Therefore, Zider is 18 days old.
Hence, this is the required solution.

PLEASE HELP, BEST ANSWER GETS BRAINIEST Each letter of the word "RESPONSIBLE" is written on a separate slip of paper and placed in a hat. 1) What is the probability of choosing an E? 2) What is the probability of choose an "E" and then an "R" without replacing the letter? Write as a fraction
Answer:
1) 2/11
2) 2/121
Step-by-step explanation:
1. Because there are 2 E's, you have to chances out of your 11 changes, thus why the fraction 2/11 is the solution.
2. You know that 2/11 is the first fraction, so now find R. R has a 1/11 chance of getting chosen, so you multiply 2/11 and 1/11 to get 2/121.
Answer:
1) 2/11

Witch three values are equivalent to 3/8?

50%
37.5%
3.75
Answer:
0.375
6/16
37.5%
Step-by-step explanation:
Can't be above 50% because that would be 4/8, which rules out 62.5%, 50%, and 3.75, and 3.75% is super low, which leaves 4 answers, but 1/4 doesn't equal any of the others. Also, 3/8 x 2 is 6/8, and 0.375 = 37.5%
Do two points always, sometimes, or never determine a line? Explain.
Answer: sometimes
explanation:
if there are two points then there could be a line to connect them, however, there could always be two points that are separate on their own.
Answer:
Always
Step-by-step explanation:
If 2 distinct points lie on the plane then it determines the line. You can also verify if you can find the slope, with these 2 coordinate points, and then find the equation of the line but using point slop form and/or slope intercept form which is y=mx+b
What is the image of the point (-5,4) after a rotation of 270° counterclockwise
about the origin?
Answer:
A counterclockwise rotation of 270º about the origin is equivalent to a clockwise rotation of 90º about the origin. Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.

5) through: (-3, 3), slope = 0
Answer:
3
Step-by-step explanation:
We know that -3 is on the x axis and 3 is on the y axis.
and the y axis usually determines if you are going to have a positive slope or negative since it would either rise or decrease. In this cause (-3, 3) shows that 3 is going to be our slope.
Answer:
y=3
Step-by-step explanation:
In a normal equation, y=mx+b, m=slope. If slope=0 in this equation, then it is safe to say that the equation is y=b. Since the Y coordinate is 3, then we can safely assume that the equation is equal to y=3
