I need help with numbers 20,21,and22

julsineya [31]

Answer:

20) the answer is -43

21) the answer is 25

22)the answer is -5

Step-by-step explanation:

20) $\frac{p(p+n^{2})}{6}$

n=-7

p=-6

we have:

$\frac{-6*(-6+(-7)^{2})}{6}\\\\\frac{-6*(-6+49)}{6}\\\\\frac{-6*(43)}{6}\\\\\frac{-258}{6} \\-43$

21) mp-(p-(m-n))

m= -1 n=-6 p=-10

-1*-10-(-10-(-1-(-6)))

10-(-10-(5))

10-(-15)

10+15=25

22) $m-\frac{m+m}{2} - n$

m=1 n=5

1- $\frac{1+1}{2} -5$

1- 2/2 -5

1-1-5 =-5
