Answer and would give multiply the following and simplify: 1. (x-2)(x-2) factorise the following quadratics: 1. x²+5x+6 2. t²+7t+10 3.r²+5r+4 4. x²+x-42 5. p²+27p+162 6. m² - 36 : )

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.
