Write a formula for the perimeter p for triangle. solve the formula for b. use the new formula to find b when a is 20 feet and c is 17 feet

i will pick c put check it over to be sure

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

answer:

idk
