For a polygon to be regular it must have all sides the same length and all interior angles the same.

Whats the answer to 8p squared minus 16 p=10

goblinko [34]

8p² - 16p = 10

8p² - 16p - 10 = 0 Divide through by 2

4p² - 8p - 5 = 0

Multiply first and last coefficients: 4*-5 = -20

We look for two numbers that multiply to give -20, and add to give -8

Those two numbers are 2 and -10.

Check: 2*-10 = -20 2 + -10 = -8

We replace the middle term of -8p in the quadratic expression with 2p -10p

4p² - 8p - 5 = 0

4p² + 2p - 10p - 5 = 0

2p(2p + 1) - 5(2p + 1) = 0

(2p + 1)(2p - 5) = 0

2p + 1 = 0 or 2p + 5 = 0

2p = 0 -1 2p = 0 - 5

2p = -1 2p = -5

p = -1/2 p = -5/2

The solutions are p = -1/2 or -5/2

Answer:

y-intercept: (0, 3)

Step-by-step explanation:

Attached is a screenshot of the plotted points (-1, 1) and (1, 5) on a graph. It shows that the line crosses the y-axis at point (0, 3) → which is the y-intercept.
