Rewrite the expression 7x^2 + 14x - 56 as three factors where one of the factors is an integer value.
choose three factors and write an equivalent expression.

options listed:
6

7

42

(x+1)

(x-1)

(x+2)

(x-2)

(x+3)

(x-3)

(x+4)

(x-4)

The factors are

Step-by-step explanation:

we have

equate the expression to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side

Rewrite as perfect squares

Take square root both sides

therefore

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

the answers might not be correct use at own risk

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
