A = nuts of $2/lb
B = nuts of $7/lb
let's say we'll mix "x" lbs of B to get a mixture with A of "y" lbs, therefore

Your answer should be 486 inches, you do 9x9 to find the area of one of the faces, and because there is 6 faces, you multiply that answer (81) to get 486
Factor and set each factor equal to zero:
x = -3, 3, 2i, -2i
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
D) because only 4 is the common factor in the equation.
