12. Find the value of m and of n for each of the following quadratic inequalities:

(a) r^2+ mr
(b) 2r^2 + m > nx which is satisfied by x < -2 or x > 5.

answer:

2 the answer is 2

Step-by-step explanation:

add

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

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
