A^3-b^3=(a-b)(a^2+ab+b^2)
a^3=64 b^3=27
a=4 b=3
Prove:
64-27=(4-3)(16+12+9)
= 37
The answer would be .430
in a decimal point
Answer:
they skided 242 feet
Step-by-step explanation:
H = height of triangle
b = length of triangle base
A = area of triangle
Recall the formula for area of a triangle :
A = 1/2 bh
Plug in what was given in the problem :
h = b - 5
A = 42
A = 1/2 bh
42 = 1/2 b (b-5)
