If x = -2 and y = 5, find the value
of the expression 5y - 3x².

=3

Step-by-step explanation:

Because....

what I did first was plug in -2 in the x's place and 5 in the y's place.

So it would look like, 5+5-3-2^2 , then you have to solve that.

Since,

Then, it would be

Add and subtract ( left to right) 5 + 5 - 3 - 4

Finally, your answer is going to be 3.

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
