11. 4p2 + 7p + 3
factoring equations

Step-by-step explanation:

Step-by-step explanation:

4p² + 7p + 3 = 4p² + 4p + 3p + 3

                    = 4p*(p + 1) + 3*(p + 1)

                    = (p + 1)(4p + 3)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8
