The are of a rectangular trampoline is 112ft. The length of the trampoline is 6ft greater than the width of the trampoline. This
situation can be represented by the equation x^2+6x-112=0 what is the width of the trampoline in feet
1 answer:
Answer:
8cm
Step-by-step explanation:
let x = width
x^2+6x-112=0
we would solve this using the factorization method
the factors of -112x^2 that would add up to 6x are 14x 8x
x^2 - 8x + 14x - 112 = 0
factorise
x(x - 8) + 14(x - 8) = 0
x+ 14 = 0
x - 8 = 0
x = 8
the width is 8cm
x = -14
