Anna leaned a ladder against the side of her house. The ladder forms a 79º angle with the ground and rests against the house at a spot that is 18 feet high. The distance along the ground from the bottom of the ladder to the wall is approximately feet. Round your answer to the nearest tenth.

The expression of this would be 3.75x+y= 23

Hope i can you!

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
