Use the difference of squares identity to write this polynomial expression in factored form: 9x2 − 49.

Step-by-step explanation:

Use the difference of squares identity to write this polynomial expression in factored form:  

Difference of square formula is

9 can be written as 3^2

49 can be written as 7^2

The value of 'a' is 3x  and b is 7

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

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
