The area = 1/2 * base * height
202.5 = 1/2 * base * 15
measure of the base = 202.5 / (1/2 * 15)
= 27 answer
Answer:
x = 8√5
Step-by-step explanation:
for right triangle
c^2 = a^2 + b^2
with c is the hypotenuse; a & b are the other sides
(4 + 16)^2 = (4√5)^2 + x^2
400 = 80 + x^2
x^2 = 320
x^2 = 64(5)
√x^2 = √64(√5)
x = 8√5
Answer:
(x + 9)(x - 8)
Step-by-step explanation:
f(x) = x^2 + x - 72
= x^2 - 8x + 9x - 72
= (x^2 - 8x) + (9x - 72)
= x(x - 8) + 9(x - 8)
= (x + 9)(x - 8)
Answer:
the Peter age be 27
Step-by-step explanation:
Let assume peter be
And, then mary is 2p ÷ 3
So
The equation would be
2p ÷ 3 - 2 = 1 ÷ 2 (p + 5)
4p - 12 = 3p + 15
p = 27
So Peter age be 27
And, the mary age is
= 2 (27) ÷ 3
= 18
Hence, the Peter age be 27
