In the equation, 4 (x + 5) - 2x + 4 = 16 , what is the first step that should be taken to solve for x?
a Distribute the four among the terms inside the parentheses
b Combine like terms.
c Subtract both sides of the equation by 4
d Divide both sides of the equation by 2

a Distribute the four among the terms inside the parentheses

Step-by-step explanation:

4 (x + 5) - 2x + 4 = 16

The first step to solve for x is to distribute the 4

4 x + 20 - 2x + 4 = 16

Then we combine like terms

2x +24 =16

Then subtract 24 from both sides

2x = -8

Then divide both sides by 2

2x/2 = -8/2

x=-4

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
