1 / 343
This is just equal to 
1 / 7^3 = 7^-3

A. 7^-1 * 7^-2 = 7^(-1 + -2) = 7^-3
B. 7^7 * 7^-10 = 7^( 7+ -10) = 7^-3
C. 7^-2 * 7^-5 = 7^(-2 + -5) = 7^-7
D. 7^-5 * 7^2 = 7^(-5 + 2) = 7^-3

So the correct answer is letter C. 7^-2 * 7^-5

What are the demensions of a rectangle if the perimiter is 20 and the area is 24
Advocard [28]

Answer:

I simply listed the factors of 24, and tested which ones worked in this equation: P = 2a + 2b.

So the factors listed were:

24 x 1

12 x 2

8 x 3

6 x 4

After testing each one of these, 6 and 4 had worked for me.

P = 2(6) + 2(4)

P = 12 + 8

P = 20

Therefore, the dimensions of this rectangle are 6 and 4.

I’ll give you 30 points if you help
KATRIN_1 [288]

Answer:

2, -2

Step-by-step explanation:

f(x) = 2x + 1

g(x) = x - 3

To find g(f(x)), you need to put f(x) into g(x).

g(f(x)) = (2x + 1) - 3

g(f(x)) = 2x + 1 - 3

g(f(x)) = 2x - 2

Your answer will be 2 and -2.
