Answer:
5. 40
Step-by-step explanation:
(14) +(4x+6) = 8x
14 + 4x+ 6 = 8x
20 = 8x - 4x
4x = 20
x = 5
RT = 8x
= 8 * 5....since x = 5
= 40
We know that
[the volume of the stack of books]=[area of each book]*[<span>height of the stack]
</span>area of each book=63 in²
height of the stack=15.75 in
<span>so
</span>[the volume of the stack of books]=[63 in²]*[15.75 in]=992.25 in³<span>
the answer is
</span>D) 992.25 in³
Answer:
Step-by-step explanation:
Slope: 7/1
y-intercept: (0,-4)
Start in the y-intercept (0,-4). Go up 7 and 1 to the right. You only need two points to trace a line.
Using Pythagorean’s theorem, the side length is sqrt(89)
