The answer should be option c
Answer:
0
Step-by-step explanation:
It is not permissible for the denominator to be zero, so the "nonpermissible replacement" for x is 0.
Its true because scalene doesn't have equal sides
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)
