PLS HELP ME I NEED ANSWER FAST

Step-by-step explanation:

(4x^3 - 4 + 7x) - ( 2x^3 - x - 8) = 2x^3 + 8x + 4

= (B)

(-3x^2 + x^4 + x) + (2x^4 - 7 + 4x) = 3x^4 - 3x^2 + 5x - 7

= (D)

(x^2 - 2x)(2x + 3) = 2x^3 - x^2 - 6x

= (A)

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
