Answer:
64x+56 & 24x+56
Step-by-step explanation:
I hope this is what you mean because this is not an equation as it is not set equal to anything.
Both problems solved by distributive property -
8*8x + (8*7) = 64x+56
8*3x + (8*7) = 24x+56
1 8/21 liters
They are none x- intercepts on the parabola. To find the x-intercept, substitute in 0 for y and solve for x.
