The answer is 6. I know that because I solved the question and I got 6 I'm positive its 6. Hope this helps.
Regroup: (4x³-12x²)+(7x-21)
factor: 4x²(x-3)+7(x-3)
factor again: (x-3)(4x²+7)
I might not be right but a is 2 and b is 16

Among the choices the <span>two statements help to prove that if segment JL is x, then x^2 = 100 is the below:
</span><span>Segment JL × segment JM = 36
Segment JL × segment LM = 64
</span>
4/7 of 49 = 28, the reason why is because if you divide 49 into 7 different groups, you will get 7 groups of 7(7x7=49). And if you take 4 of those groups, the answer is 28(7x4=28)
