F=v+at
f-v=at
(f-v)/t =a
the first choice is correct :)
Would it be 4(1)^2+2(2(1)+2)^2=100
I think it’s 9+2 because it say sum
Ac method
for
ax^2+bx+c
multiply a and c together
find what 2 numbers multiply to get ac and add to get b
split b up
gropu
factor
3x^2+7x+2
2 times 3=6
what 2 numbers multily to get 6 and ad to get 7
6 and 1
3x^2+6x+1x+2
(3x^2+6x)+(1x+2)
3x(x+2)+1(x+2)
(3x+1)(x+2) is factored
