42 - 2x is the answer because x is the variable standing in for the number that will be multiplied by 2 (2x means 2 times something) and decreased by just means minus. if you haven't gotten to doing 2x then do 42 - 2*x

The length of the sides of a triangle are x, 2x+2, and 13. If the perimeter of the triangle is 30, what is the value of x?

scZoUnD [109]

Add all the sides up to equal 30 in an equation because you are given the perimeter. The perimeter is the length around a two dimensional shape. This means the perimeter is the length of all the side lengths added together.

(x) + (2x + 2) + (13) = 30

Combine like terms.

3x + 15 = 30

Subtract 15 from both sides.

3x = 15

Divide both sides by 3.

$\boxed {x = 5}$
