X^2 + 12^2 = 13^2. (‘^2’= to 2nd power)
X^2 + 144 = 169
- 144. -144 (make X term by itself)
X^2 = 25 (to undo “squared”, find root.)
X = 5
All you have to do is multiply 84 by 25%
And that's your answer.
I hope this helped
Answer:
23
Step-by-step explanation:
area of a trapezoid = 1/2 × (a + b) × h
so, we have
96 = 1/2 × ((4x - 1) + (x + 3)) × 6 = (5x + 2) × 3
32 = 5x + 2
30 = 5x
x = 6
a = 4x - 1 = 4×6 - 1 = 24 - 1 = 23
9/7 because of order of operations
About 6.25 All you have to do is divide 16.25 by 2.6
