Answer:

2x\sqrt{15}

Step-by-step explanation:

we can use the Pythagorean Theorem to find the missing side (a):

a² + (2x)² = (8x)²

a² + 4x² = 64x²

a² = 60x²

a = √60x²

a = \sqrt{4}·\sqrt{15} · \sqrt{x^2}

This can be simplified to be 2x\sqrt{15}

$50 - ($10 + $12) = $50- $22 = $28

That is, she has $ 28 left

n: Let the variable that represents the amount of games Lauren can play.

Then, it must be fulfilled that:

0.75n \leq28\\n \leq \frac {28} {0.75}\\n \leq37.33
