Hello, there!
He could use answer D. 8 feet by 3 feet.
The formula for area of a rectangle is L * W = A
The length is 8 and and the width is height
8 * 3 = A
8 * 3 = 24
Therefore, the answer is D.
I hope helped!
Let me know if you need anything else!

I think the answer is the first one and the last one .
(x, y ) = (- 6, 3 )
Since both equations express y in terms of x, we can equate them
2x + 15 = - 
x + 1
( add x to both sides )
x + 15 = 1 ( subtract 15 from both sides )
x = - 14
( multiply both sides by 3 and divide by 7 )
x = ( 3 × - 14 )/7 = - 6
substitute x = - 6 into either of the 2 equations for y- coordinate )
y = ( 2 × - 6 ) + 15 = 3
solution : (x, y ) = ( - 6, 3 )

Vc = L * W * h = 0.25 * 0.25 * 0.25 = (0.25)^3 = 0.0156 in^3 = Volume of cube
Vr / Vc = 14.22in^3 / 0.0156in^3 = 910 cubes910 cubes are needed to fill the rectangular prism.

Answer:
c
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and
b is the y-intercept.
y=mx+b
m=−3
b=0
y=-3x+0
