Complete the work shown to answer the question. p2 – 14p – 72 = 0 p2 – 14p = 72 p2 – 14p + 49 = 72 + 49 which describes the solutions of the equation? since 7 and 11 are both rational, the sum and difference are rational. since 14 and 11 are both rational, the sum and difference are rational. since 7 is rational and is irrational, the sum and difference are irrational. since is irrational and 11 is rational, the sum and difference are irrational.

Since 7 and 11 are both rational, the sum and difference are rational.

a. Since 7 and 11 are both rational, the sum and difference are rational.  

Step-by-step explanation:

p^2 – 14p – 72 = 0

p^2 – 14p = 72

p^2 – 14p + 49 = 72 + 49

p^2 – 14p + 7^2 = 11^2

(p - 7)^2 = 121

taking square roots in both sides

p - 7 = ± 11

This procedure was made knowing that 7 and 11 are both rational

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
