Answer:
Take 4.25 x 8.6= 36.55 feet^2
Step-by-step explanation:
Answer:
-45.
Step-by-step explanation:
I am assuming you mean
√25 - 2(3 +4(-2))^2
= 5 - 2(3-8)^2
= 5 - 2 * (-5)^2
= 5 - 2*25
= -45.
Answer: ![\frac{x^{20}}{y^{15}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B20%7D%7D%7By%5E%7B15%7D%7D)
This is the same as writing (x^20)/(y^15)
===================================================
Work Shown:
![\left(x^{-4}y^3\right)^{-5}\\\\\left(x^{-4}\right)^{-5}*\left(y^3\right)^{-5}\\\\x^{-4*(-5)}y^{3*(-5)}\\\\x^{20}y^{-15}\\\\\frac{x^{20}}{y^{15}}](https://tex.z-dn.net/?f=%5Cleft%28x%5E%7B-4%7Dy%5E3%5Cright%29%5E%7B-5%7D%5C%5C%5C%5C%5Cleft%28x%5E%7B-4%7D%5Cright%29%5E%7B-5%7D%2A%5Cleft%28y%5E3%5Cright%29%5E%7B-5%7D%5C%5C%5C%5Cx%5E%7B-4%2A%28-5%29%7Dy%5E%7B3%2A%28-5%29%7D%5C%5C%5C%5Cx%5E%7B20%7Dy%5E%7B-15%7D%5C%5C%5C%5C%5Cfrac%7Bx%5E%7B20%7D%7D%7By%5E%7B15%7D%7D)
In the second step, I used the rule that (a*b)^c = (a^c)*(b^c)
In step 3, I used the rule (a^b)^c = a^(b*c)
In the last step, I used the rule a^(-b) = 1/(a^b)
The answer is A and D -30+d but you can also get the answer by multiplying like lets say d=2 30+30=60 and 30*2=60.
