You have to find the measure of angle QPR.

Solve:

$40 = 8x + 7 + 9x + 16$

Add like terms

$40 = 17x + 23$

Solve

$40 - 23 = 17x + 23 - 23$

$17 = 17x\\\frac{17}{17} = \frac{17}{17}x\\1 = x$

Plug in x to solve for the angle measure of QPR

$9(1) + 16 =\\9 + 16 =\\25$

The angle measure of QPR is 25°

Answer:

I'm going to assume that you meant y=3x-8 and y=-4

This means that you would substitute -4 into the spot of y which gives you -4=3x-8. Once solved you would receive x=4/3.

Hope I helped have a nice day :)

a(t)=(t−k)(t−3)(t−6)(t+3) is a polynomial function of tt, where kk is a constant. Given that a(2)=0a(2)=0, what is the absolute

Crank

Since $a(2)=0$ , we know that $t-2$ must be a factor of $a(t)$ , so $k=2$ . Then the zeros of $a(t)$ are $t=2,3,6,-3$ , and their product is -108, whose absolute value is 108.
