What is the answer and answer it completely

3 + 2(x + 4)(x - 4)

3 + 2(x^2 - 4x + 4x - 16)

3 + 2(x^2 - 16)

3 + 2x^2 - 32

2x^2 - 29

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
