Please help !! Problem A painter is painting a mural on a wall. He has a 20-foot ladder. He needs to work on
a part of the wall that is 16 feet above the ground. How far from the base of the building should
he place the foot of the ladder to make sure that the ladder reaches his work area? Show your
work

The worker should put the ladder 4 feet away from the wall.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
