Evaluate the following algebraic expression when x = 3 22+ 5x - 10 pls help me with this it’s so confusing

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

answer: 1/2=3/6=4=8

step-by-step explanation:

3/6= 1/2

4/8=1/2

your answer is 2 yeah bo
