Answer:
V(x) = l*w*x - 2*l*x² - 2*w*x² + 4*x³
Step-by-step explanation:
The volume of any box is:
a * b * h where a is the length, b is the wide and h is the height
Assuming we have cardboard of dimensions: l * w
l - 2*x will be length of the box and
w - 2*x will be wide of the box
h = x the height, then:
V(x) = ( l - 2*x ) * ( w - 2*x ) * x
V(x) = [ ( l*w - 2*l*x - 2*w*x + 4*x² ] * x
V(x) = l*w*x - 2*l*x² - 2*w*x² + 4*x³
9 hearts on card 3 and 6 squares on card 3
50 x 32 = 1600square feet
area of a square is S^2 so the length of the side of a square would be 1600 =S^2
S=sqrt(1600) = 40 feet long
perimeter of a square is 40 x 4 = 160 feet
Answer:
35 1/12 gallons of gasoline
Step-by-step explanation:
so what you're going to do is take both of the fractions (3/4 and 1/3) and convert them into two fractions with the same denominator so you can add them easily. the closest number that you can convert them to would be a denominator of 12, so we would turn 3/4 into its equivalent of 9/12 and 1/3 would now be 4/12. now we add them and get 13/12, which is an improper fraction, so we would change that to 1 and 1/12. and finally, we add 1 1/12 + 1 + 33 and we would get 35 and 1/12 as our final answer :)
