to find SQR you need to subtract the value of RQP (37) from the value of PQS (80).
so 80-37= 43
SQR=43
Step-by-step explanation:
22+2x+8= x+20
2x+30=x+20
x+30=20
x=-10
answer is -10

To answer this question, we need to first know what f(x) means. For example, if f(10), then you plug in 10 for x, 7(10)+2 = 72.
Do the same thing but with f(7).
f(7) = 7(7)+2
f(7) = 49+2
f(7) = 51
Hope this helps.
Answer:
x = 2√13
Step-by-step explanation:
First, we can put out a lot of equations to see if we can make a system:
<em>x² = y² + 4²</em>, x² + z² = 13², xz = 13y, <em>y² + 9² = z²</em>
Substitute 4 into 1: <em>x² = (z² - 9²) + 4²</em>
System 2 and substitution: <em>x² + z² = 169, x² - z² = -65</em>
Elimination: 2x² = 104
Divide: x² = 52
Square root: x = √52 = 2√13
