x=14

In the second line, he changed the sign on the 2

Step-by-step explanation:

2(3x-4) = 5x+6

Distribute the 2

6x-8 = 5x+6

Subtract 5x from each side

6x-5x -8 = 5x-5x+6

Add 8 to each side

x-8+8 = 6+8

x=14

b.  4x-3 = 2(x-1)

Distribute

4x-3 =2x-2    He changed the sign on the 2

Subtract 2x from each side

4x-2x -3 = 2x-2x-2

2x-3 =-2

Add 3 to each side

2x-3+3 =-2+3

2x =1

Divide by 2

2x/2 =1/2

x=1/2

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

answer:
