Answer:
90 pumpkin and 36 green beans
Step-by-step explanation:
Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.
Answer:
-4, -2, 0 or -8, -6, -4
Step-by-step explanation:
#1 =x
#2 = x+2
#3 = x+4
x(x+2) = -10(x+4) + 8
x^2 + 2x = -10x - 40 + 8
x^2 + 12x + 32 = 0
(x+8)(x+4) = 0
x = -8 or x = -4 so:
#1 = -8 or -4
#2 = -6 or -2
#3 = -4 or 0
