6^2 is rational because it equals 36 which is a rational number.
Answer:
assuming x2 is x^2:
f(x) = (x+4)^2 - 3
Step-by-step explanation:
1. move c to f(x) side
2. make sure a=1
3. (b/2)^2
4. add the solution of 3 on both sides
5. factor the right side using the shortcut
6. add c back to the other side
9, I believe.
4(2)+2(1)^2-(1)^3 (^ just means to the power of "exponent")
8+2-1=9
Answer:
B
Step-by-step explanation:
r=q+10.1
• take q=5 then r= 5+10.1= 15.1
• take q=7 then r= 7+10.1= 17.1
• take q=9 then r= 9+10.1= 19.1
• take q=11 then r= 11+10.1= 21.1
