Answer:

You could use a graphing calculator to see the lowest point in the graph OR you could put that equation into it's completed squared form, which is (x-4)^2 -4. The opposite of -4 in the parentheses is positive 4, and the leftover -4 is the y value. So that also becomes (4,-4)

2 angle A and B are Complementary means that the sum of their measures is 90°.

2 angle A and B are Supplementary means that the sum of their measures is 180°.

Thus, if the measure of angle A is x:

the measure of the supplement is 180°-x
the measure of the complement is 90°-x

"The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. "

let the measure of the angle be x, then we have:

180°-x=40°+2(90°-x)

180°-x=40°+180°-2x

2x-x=40°

x=40°

Answer: 40°

Answer:

$3 (a-2) (a-5)$

Step-by-step explanation:

The first step is to find the GCF. Here, it's 3.

$3(a^2-7a+10)$

Then, you factor the polynomial in the parenthesis.

To find the factors, you will need to find 2 numbers that add to -7, and multiply to 10. -2 and -5 add to -7 and multiply to 10. Now, replace -7a with the factors.

$a^2-2a-5a+10$
