Is c the correct answer or?

I think yes it's correct but I'm not sure.

C=20 units (They didn't give the unit in the problem so if you want just write 20.)

Step-by-step explanation:

You need to solve for c. So first you have to use the equation.

We already know a and b so no we plug them in.

16^2 + 12^2 = c^2

When a number is squared or written as to the power of two you simply have to multiply that number by itself. So 16^2=256 and 12*12=144

256+144=c^2

c^2=400

Now we have to do another step because we don't want to know c^2 but want to know c. Now we have to find the square root of 400. The answer is 20 because 20*20=400.

me! what did you put for this question?

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
