Solve the system of equations
x+y+z=3
2x+5y+2z=3
-x+9y-3z=21

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

milk=16 large

soda=280 kids

juice box=82 regular
