Answer:

<h2> x = 15</h2>

Step-by-step explanation:

RQ < PR < PQ

TV < UV < UT

ΔPQR~ΔUTV ⇒ $\dfrac{RQ}{TV}=\dfrac{PR}{UV}$

$\dfrac{8}{x-3}=\dfrac{14}{x+6}\\\\8(x+6)=14(x-3)\\\\8x+48=14x-42\\\\48+42=14x-8x\\\\90=6x\\\\x=90:6=15$

What is the math term for you taking parentheses away?

TEA [102]

You might be thinking of "distribution" or "distributive property"

Example:

2(3x+5) = 2*3x+2*5 = 6x+10

I multiplied the outer 2 by each term inside (3x and 5)
