8. b
9. d
Step-by-step explanation:
1: 1, 2, 3, 4, 5, 6, 7, 8, 8, 9, 10....
2: 2, 4, 6, 8, 10....
3: 3, 6, 9, 12, 15, 18, 21, 24, 27....
4: 4, 8, 12, 16, 20, 24, 28, 30....
5: 5, 10, 15, 20, 25, 30, 35 40, 45...

(7^1/2)^2=7^(1/2*2)=7
To solve for b, we want to use the Pythagorean Theorem as given.
b and 7 are the legs, and 12 is the hypotenuse.
[exponent]
[subtract both sides by 49]
[square root both sides]
Now we know .
p=-7 :)
-13-8=3p
-13+(-8)=3p
-21=3p
÷3
-7=p
x=4/3
