First, we can simplify it down. 
x = (-x + 6)^2
Then, you should have x - (x^{2} - 12x + 36).
Factor it to get x = 4 or 9. 4 works in the original equation but 9 does not.

=0.56x−0.25n=0.20x−0.03
katovenus [111]

Given:

m=0.56x-0.25

n=0.20x-0.03

To find:

The sum of m and n.

Solution:

We have,

m=0.56x-0.25

n=0.20x-0.03

The sum of m and n is:

m+n=(0.56x-0.25)+(0.20x-0.03)

Combining the like terms, we get

m+n=(0.56x+0.20x)+(-0.25-0.03)

m+n=(0.76x)+(-0.28)

m+n=0.76x-0.28

Therefore, the sum of m and n is m+n=0.76x-0.28.

1 and 2 are complementary angles. 1 and 3 are vertical angles. If
Marizza181 [45]

If angle 1 and angle 2 are <u>complementary, </u>then they add up to 90 degrees. We are given that angle 2 equals 52 degrees.

So we subtract and get our answer:

38

That's NOT the final answer.

The next step is:

Angle 1 and angle 3 are vertical angles.

Vertical angles are congruent.

So if angle 1 is 38, then angle 3 is also 38.

Now, supplementary angles add up to 180 degrees.

So that's the answer:

180-38=142

142 is the supplement of angle 3.

Hope it helps! :)
