Answer:
x^4/x^2 = 49
Step-by-step explanation:
First, you want to simplify the first response.
x^9/x^7 = 49
9 - 7 = 2
x^2 = 49
x = 7
You would then simplify the second equation
x^4/x^2 = ?
4 - 2 = 2
x^2 = ?
Substitute in the 7
7^2 = ?
49 = ?
12) the radius is 15 so with the equation (3.14)*r^2, we get (3.14)(15^2)=706.5
13) true, true (if x=4), true
14) y=0.75x+4.50, $8.25
60
220*2 = 440
+ 220/2 = 550
= 21 x 21 x 21 x 21 x 21 x 5 = 20 420 505
