Answer:
3√2
Step-by-step explanation:
1(3√2)2=2n
Multiply 2 and 1 to give 2
2(3√2)=2n
Multiply 2 and 3√2=6√2
6√2=2n
Divide both sides by 2
n=6√2/2=3√2
B and C I believe .............
Answer:
264 with a remainder of 4
Step-by-step explanation:
F(x)=x^2 +8x
f(d-3) basically what we get from this is that the x value is d-3
to find f(d-3) simply plug in d-3 for every x
f(d-3)=(d-3)^2 + 8(d-3)
that would be one form of the answer, but we can also continue multiplying it out
f(d-3)= d^2-6d+9+8d-24
add like terms
f(d-3)=d^2+2d-15
have a nice day and i hope this helps :)
