What are the solutions to 7x2−15x−18=0? A x=−37 and x = 6
B x=−6 and x=37
C x=−67 and x = 3
D x=−3 and x=67

C.) X=3 and X=-6/7

Step-by-step explanation:

Use the quadratic formula to solve

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

i think the answer is b.

step-by-step explanation:

not 100% sure though.
