Answer: A and D
Step-by-step explanation:
is a rational number because when calculate the square root 400 you get 20.
is a rational number. The area of the square would be perfect square because 20*20=400. A and D are the correct answers.
Answer:
option B
Step-by-step explanation:
(6x^2-x+8) - (x^2+2)
6x^2-x+8 - x^2-2
5x^2-x+6
Answer:
D
Step-by-step explanation:
Set up to different integrals that match the endpoints
so in our case it would look like
![\int\limits^0_{-2} {x} \, dx +\int\limits^1_0 {x+1} \, dx](https://tex.z-dn.net/?f=%5Cint%5Climits%5E0_%7B-2%7D%20%7Bx%7D%20%5C%2C%20dx%20%2B%5Cint%5Climits%5E1_0%20%7Bx%2B1%7D%20%5C%2C%20dx)
now it's just a matter of computing it
![\int\limits^0_{-2} {x} \, dx =x^2\\0^2-(-2)^2=4\\\int\limits^1_0 {x+1} \, dx =\frac{x^2}{2}+x\\\frac{1}{2}+1-0=\frac{3}{2}\\\frac{3}{2}+4=\frac{11}{2}](https://tex.z-dn.net/?f=%5Cint%5Climits%5E0_%7B-2%7D%20%7Bx%7D%20%5C%2C%20dx%20%3Dx%5E2%5C%5C0%5E2-%28-2%29%5E2%3D4%5C%5C%5Cint%5Climits%5E1_0%20%7Bx%2B1%7D%20%5C%2C%20dx%20%3D%5Cfrac%7Bx%5E2%7D%7B2%7D%2Bx%5C%5C%5Cfrac%7B1%7D%7B2%7D%2B1-0%3D%5Cfrac%7B3%7D%7B2%7D%5C%5C%5Cfrac%7B3%7D%7B2%7D%2B4%3D%5Cfrac%7B11%7D%7B2%7D)
P=1/5. factor out the p to get 4p-15pn=4/5p-3n and just solve to get p=1/5
