Answer:

A.

\sqrt{500}

Step-by-step explanation:

when a value is outside of the root, then you can square it and put it back in. After you put it back in, you need to multiply it by the number that is remaining

In this case, you would square 10 which equals 100, and put it back into the root and multiply 100 by 5.

100x5=500

Therefore, the answer is A, root 500

Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1). (1 point)
mylen [45]

Answer:

-6

Step-by-step explanation:

Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly

f(x) = 12 / 4x +2

Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side

f(-1) = 12/ 4(-1) + 2

f(-1) = 12 / - 4+2

= 12/ - 2

= - 6

Does anybody know this? I don't get it.​
Tasya [4]

Answer:

scale factor = 1/2

Step-by-step explanation:

for AC: 4 + 4 = 8

8 is the AC of the red triangle

4 is the AC of the blue triangle

to get from 8 to 4, we divide by 2 or multiply by 1/2 (they mean the same thing)

10 is the CB of the red triangle

5 is the CB of the blue triangle

to get from 10 to 5, we divide by 2 or multiply by 1/2
