2(3x -1) +2(4x + 5) = 8 what's the answer and how do you solve this ?

2(3x - 1) + 2(4x + 5) = 8

Distribute the 2's inside their respective parentheses.

6x - 2 + 8x + 10 = 8

Combine like terms (6x + 8x) and (-2 + 10).

14x + 8 = 8

Subtract 8 from both sides.

14x = 0

Divide both sides by 14.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

50
