First you follow PEMDAS, doing the parentheses first. Inside the parenthesis, there is 9. 9^2 is 81. Then you multiply 15 by 81, and you get 1215. Final answer 1215

Triangle P R Q is shown. The length of side P R is 5 n. The length of side R Q is 32 + n. Angles R P Q and P Q R are congruent.

snow_tiger [21]

Answer:

Step-by-step explanation:

According to Triangle P R Q, if angles R P Q and P Q R are congruent, this means that two of the sides of the triangle a re also congruent (Isosceles triangle).

We can say then that length of side PR is equal to that of RQ i.e PR = RQ

Given

PR = 5n

RQ = 32+n

Required

Length of PR

Since the two sides are equal i.e PR = RQ

5n = 32+n

5n - n = 32

4n = 32

n = 32/8

n = 4

Get PR;

Since PR = 5n

PR = 5(4)

PR = 20

Hence the length of PR is 20.

Question 29 of 40<br> Find f(-2) for f(x) = 5.3*.

blsea [12.9K]

Answer:

A. $\frac{5}{9}$

Step-by-step explanation:

To find f(-2) in f(x)=5*3^x, plug in -2 into all the x values.

f(-2)=5*3^-2, you can use calculator to calculate 3^-2 which equals 0.1, forever 1's.

f(-2)=5*0.1=0.5 Forever 5's.

f(-2)=0.5 or $\frac{5}{9}$

Hope this helps!

If not, I am sorry.
