4(2x-4)^2 - 3
4(4x^2 - 2(4)(2x) + 16) - 3
4(4x^2 -16x + 16) - 3
16x^2 - 32x + 32 - 3
16x^2 - 32x + 29
Answer:
1/4h
Step-by-step explanation:
The car trip is 1/2h shorter than the bus trip.
The bus trip is 3/4h long.
Therefore, the length of the car trip is:
3/4h - 1/2h = 1/4h
The car trip is 1/4h long.
A + -5 = -12
A - 5 = -12
A = -7.
This is the solution.
