Me with this math will give stars, , and josh solved the equation below. is his solution correct? explain why or why not. ( show work) x^2-6x-7=0 x^2-6x+7\x^2-6x+9=7+9 (x-3)^2=16 x-3=16 x=19 x-3=-16 x=-13 i am pretty sure he messed up when he decided he needed to do x-3 twice, because when there is a +/- sign is the only time you would do x-3 then x+3, right?

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

r and t.

both are 64 degrees.
