Answer:
960
Step-by-step explanation:
LxWxH = v
V = 20x 6 x 8
Before we do any solving, we need to simplify both sides.
On the left, we can simplify -2x + 3x - 5 to x - 5.
On the right, we can simplify 6 - 21 to -16.
So we have x - 5 = -16.
Solving from here, we add 5 to both sides to get x = -11.
let's notice the tickmarks on the left and right sides, meaning those two sides are twins, and therefore equal, so the perimeter is simply 2.5+2.5+3.5+2.5 = 11 ft.
the trapezoid has an altitude/height of 2 ft, thus
Answer:
x = 6
Step-by-step explanation:
3x + 16 = 34
34 - 16 = 18
3 x ? = 18
3 x (6) = 18
18 + 16 = 34
Hope this helps :D
