Answer: The answer is A : 6x^2+24x+24
Step-by-step explanation:
(2x+4)(3x+6)
multiple the two equations together
2x*3x=6x^2
2x*6=12x
4*3x=12x
4*6=24
combine like terms
6x^2+12x+12x+24
6x^2+24x+24
EDIT: MY ANSWER ASSUMED CONSTANT ACCELERATION - CHANGING IT NOW
(6•2 - 3 - 5•3) - (4•3 + 2•2 - 8)
(12 - 3 - 15) - (12 + 4 - 8)
(9 - 15) - (16 - 8)
(-6) - (8)
-14
Change everything into 10ths as follows:
1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.
