Answer:
(5x-1)(5x+1)
Step-by-step explanation:
A = bh
b = 4h
A = 324
324 = 4h * h
324 = 4h^2
324/4 = h^2
81 = h^2
sqrt 81 = h
9 = h
b = 4h
b = 4(9)
b = 36
so the height (h) = 9 cm and the base (b) = 36 cm
Answer:
Angle bisector
Step-by-step explanation:
Bisector means that the two angles have the same measure and it is an angle bisector because it is separating angles.
The answer is 14 because a negative number multiplied by another negative number is positive. So (-7)*(-2) is 14.
Answer:
8.5 ft.
Step-by-step explanation:
We'll use this right triangular prism volume formula: base area x height = volume
base area = ?
length = 10.8
volume = 91.8
base area x 10.8 = 91.8
Divide both sides by 10.8
base area x 10.8/10.8 = 91.8/10.8
base area = 8.5
