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

3^3 . x^2- 25 divided by 5 when x= 0.6

Alenkasestr [34]

Hey there!

3^3 * x^2 - 25 / 5

= 3^3 * 0.6^2 - 25 / 5

= 3 * 3 * 3 * 0.6 * 0.6 - 25 / 5

= 9 * 3 * 0.6 * 0.6 - 25 / 5

= 27 * 0.36 - 25 / 5

= 9.72 - 25 / 5

= 9.72 - 5

= 4.72

Therefore, your answer is: 4.72

Good luck on your assignment & enjoy your day!
