How do you simplify
(3x+4y)^2 ?

(3x−4y)^2

Step-by-step explanation:

Rewrite

(3x−4y)2 as

(3x−4y)(3x−4y)

(3x−4)(3x−4y)

Expand

(3x−4y)(3x−4y)

3x(3x)+3x(−4y)−4y(3x)−4y(−4y)

Simplify and combine like terms.

9^2−24xy+16y^2

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
