Three times the square of a number means 
Nine times a number is 
If these quantities must be equal, we have

We can divide both sides by 3 to get

Since x is non-zero, we can divide both sides by x:

Step-by-step explanation:
Given f(x) = 5x - 7 and g(x) = x² - 3, find f(f(2))
Answer:
The length of the rectangle is 159923.5 and the width of 53289.5
Step-by-step explanation:
We will make 2 equations one that is the perimeter and another that is the length with respect to the width
b = w*3+55
2b + 2 w = 426426
we will replace b with (w * 3 + 55) in the second equation
2b + 2 w = 426426
2(w*3+55) + 2w = 426426
we clear w to find its value
6w + 110 + 2w = 426426
8w = 426426 - 110
8w = 426316
w = 426316/8
w = 53289.5
Now that we have the value of w we replace it in the first equation and solve to find b
b = w*3 + 55
b = 53289.5*3 + 55
b = 159868.5 + 55
b = 159923.5
Answer:
54 degrees
Step-by-step explanation:
I know this because complementary means both angles equal 90 degrees so we know the angle A is 36 degrees so you subtract 36 from 90 and get 54, so angle B is 54 (i know this is right because i got a 100)
Thank you for posting your question here at brainly. If point B on the pre-image lies at (3, 4), the are the coordinates of B'' on the final is (5, -6). Below is the solutions, I hope the answer helps.
rx-axis ◦ T2,2 (3,4)
<span>= rx-axis ( T2,2 (3,4) ) </span>
<span>= rx-axis ( 5,6 ) </span>
= (5, -6)
