(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!
Sidana [21]

Answer:

-2p^2-11p-35

Step-by-step explanation:

-2(p+4)^2-3+5p

First we square the parenthesis. Apply FOIL method to multiply

(p+4)^2= (p+4)(p+4)= p^2 + 4p+4p+16= p^2+8p+16

-2(p^2+8p+16) -3+5p

distribute -2 inside the parenthesis

-2p^2-16p-32-3+5p

Now combine like terms

-2p^2-11p-35

ratelena [41]

Answer:

The correct answer would be $126.00

Step-by-step explanation:

If you see how many times 40% goes into 100%, it would be 2.5 times. Then you multiply the 40% of the overall price ($50.40) times 2.5 and that gives you $126.

Hope this helps!!

4x-6>22 explain or prove if 5 or 8 is a solution to the inequality
babunello [35]

Answer:

8

Step-by-step explanation:

4(5) - 6 = 14

14 is not larger than 22, so 5 is not the solution.

4(8) - 6 = 26

26 is larger than 22, so 8 is the solution
