Expand and simplify 2(x+7)+3(x+1)

5x+17

Step-by-step explanation:

1.) distribute/multiply the 2 into (x+7) and you get 2x+14

2.) then do the same with the 3 into (x+1) and you get 3x+3

3.) finally, just combine the like terms which are 3x and 2x (just add them), and 14 and 3 (again add them) and your final answer should be 5x+17

2160ft3

step-by-step explanation:

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
