18. 9 decreased by twice a number is equal to 9. 9. What is the number?
Twice means two times
18.9 - 2x = 9.9
18.9 -18.9 -2x=9.9 - 18.9
-2x=9.9 - 18.9
(-2x= -9) divide both sides by negative two
-2x/-2 = -9/-2
x=4.5

Answer for 20 points
The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³
What is volume?
Volume is the amount of space occupied by a three dimensional shape or object.
The volume of a rectangular prism is given by:
Volume = length * width * height
a) Dimensions: 4 in., 3 in., 6 in.
Volume = 4 * 3 * 6 = 72 in³
b) Dimensions: 6 in., 3 in., 2 in.
Volume = 6 * 3 * 2 = 36 in³
c) Dimensions: 4 in., 5 in., 4 in.
Volume = 4 * 5 * 4 = 80 in³
d) Dimensions: 2 in., 9 in., 3 in.
Volume = 2 * 9 * 3 = 54 in³
The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

The rate of change or essentially the slope is a numerical value that describes the direction and the steepness of the line.
To find the slope, we just need any two points on the line
--> Let's pick (0,2) and (2,6)
The slope's equation = [tex]\frac{y2-y1}{x2-x1}[/tex]
Let's plug the known quantities into the equation
[tex]\frac{y2-y1}{x2-x1}=\frac{6-2}{2-0} =\frac{4}{2} =2[/tex]
Therefore the rate of change is 2 km/trip

bill can mow a lawn in 40min and jhon can mow for 60min.how long will it take to mow together
24 minutes.
Let me explain.
The lawn can be any size, but for the purpose of simplicity, let's say it's 240 square meters.
Peter mows 6 square meters per minute if he mows 240 square meters in 40 minutes.
John mows 4 square metres each minute if he mows 240 square metres in 60 minutes.
They'll mow 10 square meters per minute if they work together.
As a result, mowing the entire lawn will take them 24 minutes.
(Note that the location is irrelevant as long as we know how long each man takes to complete the task separately.) The answer would be the same if the field was 1 million hectares in size.)
I hope this helps.
Explain How you get -8 whe solving -5+-3
Answer:
-5+(-3)
=-5-3
=-8
Step-by-step explanation:In a problem like this you have to write -3 in parentheses.
Since the + sign is outside the parentheses here, the -3 and + sign are multiplied.
+ saha- multiplication yields -sign.
So there's a -3 coming.
Then -5-3.
Since the sign of this is the same, the two numbers are added. In both - the mark is applied to the answer because there is a mark.

Which function is a quadratic function? p(x) = 2x(x2 6) 1 m(x) = –4(x 3) – 2 t(x) = –8x2(x2 – 6) 1 h(x) = 3x(x – 2) – 4.
The function represent the quadratic function is h(x) = 3x(x – 2) – 4, the correct option is D.
What is Quadratic funtion?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c where a, b, c, ∈ R and a ≠ 0.
The function which represnt a quadratic function is;
[tex]\rm h(x) = 3x(x - 2) - 4\\\\ h(x)=3x\times x - 3x \times 2-4\\\\ h(x)=3x^2-6x-4[/tex]
The highest degree of the function is 2 so the function is the quadraic function.
Hence, the function represent the quadratic function is h(x) = 3x(x – 2) – 4.
