The roots of a quadratic equation are -7 and 1. write an equation that could represent this function. give your answer in standard form and factored form.

Step-by-step explanation:

equation -

(X+7) (x-1) =0

equation = x2 -x -7x -7 = x2 -8x -7

standard form = x2 -8x -7

factor form = (x+7) (x-1)

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
