Solve the following equation for x. -5(x + 4)= 12 – 40 – 70

x = 78 /5

Step-by-step explanation:

5(x+4)=12-40-7x

Subtract the numbers from the left side which will equal -25-7x

Then... Distribute the -5 to x and 4 making the equation on the left

-5x -20

In all your equation should look like this

-5x -20 = -25 -7x

Then add 7x to the right side and add 20 to the left making the equation

-5x + 7x = -28 + 20

The add up the terms on each side...

2x = -8

Then divide the 2 to the left side...

Overall:

x= -4

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
