Answer:
Final factor is (x-9)(x+4)
Step-by-step explanation:
Given expression is
.
Now we need to factor that expression

Find two numbers whose product is -36 and sum is -5.
Two such numbers oare -9 and +4. So we get:



Hence final factor is (x-9)(x+4)
We want to replace x with 2x in the original equation
g(2x) = 3(2x) -5
We can multiply 3 and 2x to simplify this, which will give us 6x
g(2x) = 6x - 5
Answer:
96
Step-by-step explanation:
Total area = area of cube + area of triangle
A = 8² + = 64 + 32 = 96 in
