We know that
[the surface area]=2*[area of the base]+[perimeter of the base]*height
[the surface area]=2*[8*2.5]+[2*(8+2.5)]*12
[the surface area]=40+252-----> 292 in²
the answer is
<span>the least amount of cardboard needed to make the cereal box is 292 in</span>²
First you need to find the y-intercept, which is y = -1
Next is we need to find the slope of the line > you are going to have to do this by finding to clear point
The ones that I will be using are: (3, 1); (6, 3) (You could take any points)
Now using the slope formula we could find m.
m = y2-y1 / x2-x1
(1 - 3) / (3 - 6) = m
-2 / -3 = m
m = 2/3
Using the linear function format: y = mx + b
Therefore the equation of the line is y = 2x/3 -1
For this case we have to:
x: Let the variable representing the unknown number
We algebraically rewrite the given expression:
Eleven more than four times a number, is represented as:
The number less 7, is represented as:
Thus, the complete expression is:
We subtract x from both sides of the equation:
We subtract 11 from both sides of the equation:
Equal signs are added and the same sign is placed:
We divide by 3 on both sides of the equation:
