Answer: 4 • (3x - 5)2
Step-by-step explanation: ((22•32x2) - 120x) + 100
Given:
The given expression is:

To find:
Part A: The expression by factoring out the greatest common factor.
Part B: Factor the entire expression completely.
Solution:
Part A:
We have,

Taking out the highest common factor 3y, we get

Therefore, the required expression is
.
Part B:
From part A, we have,

By grouping method, we get


Therefore, the required factored form of the given expression is
.
The equation would be: 16(4)+.15m=79
The answer would be 100 miles.
Plug into calculator...
solve(2(-y+1)-3y=-30,y)
y=6.4
