find the volume of a rectangular prism if the length is 4x, the width is 5x, and the height is x2 + x + 2. use the formula
v = 1.w h, where i is length, w is width, and his height, to find the volume. (6 points)
20x3 + 20x2 + 40x

0
20x4 + 20x3 + 40x2
20x* + x + 29
20x4 + 9x3 + 18x2

if x decreases by 4 then y increases by 10

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

good luck on your studies! : )
