Answer:
and 
Step-by-step explanation:
Think about it.
What two numbers multiply to -15 and add up to 2?
The answers are 5 and -3.
So plug that into the factored form of a parabola.

To find the x-intercepts, plug in 0 for
.

Since we are multiplying, at least one of the terms has to equal 0.

So the x-intercepts are
and
.
Answer:
Step-by-step explanation:
One - third = 1/3
then:
one third of a number = a*1/3 = a/3
Then the equation that represents this sentence is:
2 + a/3 = 8
process:
a/3 = 8 - 2
a/3 = 6
a = 6*3
a = 18
Check:
2 + 18/3 = 8
2 + 6 = 8
Your right it’s an obtuse angle
Answer:
AC = 15, CM = 20, CP = 12
Step-by-step explanation:
see the attached picture, I tried to explain as much as possible, the general idea is there are three triangles that are similar to one another and thus in proportion. Therefore you can find missing sides using ratios.
This would be 198 because 12 times 1.5 equals 18 so when you multiply 132 by 1.5 you get 198
