Each can of tennis balls has $x$ balls. Initially, Sam has 14 cans of tennis balls, plus 3 extra balls. Jerri initially has 7 cans of tennis balls, plus 8 extra balls. If Jerri doubles the number of tennis balls she has, how many more balls will she have than Sam has? NEED ASAP PLS

13balls

Step-by-step explanation:

2(7x+8)-14x+3=? distribute

14x+16-14x+3 do like terms

14x-14x cancel

16-3 =13

it may seem confusing in the explanation but i hope that helps.

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
