when x-3, both expressions have a value of 30.
when x-5, both expressions have a value of 42.
when x= 1, both expressions have a value of 18, and when x=8, both expressions have a value of 60.
when x = 2, both expressions have a value of 15, and when x=6, both expressions have a value of 39.

because its not ur topic and its not for is for homework not that.

your answer is a

step-by-step explanation:

4*4*4*4=256

a is the correct

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
