Write an expression in terms of n
adds 2 to the number and then multiplies the result by 3

Step-by-step explanation:

Let the number = n

Add 2 to the number : n + 2

Multiply the result by 3 : (n + 2) *3

                                      = n * 3 + 2*3

                                      = 3n + 6

is this a multiple choice question?

if so it's a and c

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
