Are you able to expand everything first? from there you would be able to combine line terms. basically if you have 3x+2x it would combine to 5x because they have x in them.

2(x/2 -5)-3/2(x+7/4)
= x-10-3x/2-21/8
Then we,combine like terms;
= -x/2-101/8
Then,take out -1/2 to simply the equation.

= -1/2(x+101/4)

A right triangle has a base that measure 39 inches and a height that measures 80 inches. What is the length of its hypotenuse?

guajiro [1.7K]

The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
