An open box is formed by cutting squares with side lengths of 3 inches from each corner of a square piece of paper. what is a si

The volume formula for a square or a rectangle, even, is V=l*w*h
Here, we are given our volume as 675, now we just have to find everything else, right?! Well, if you have a square, all 4 sides are the same exact length, so the length and the width of our formula are going to be the same so we only have to worry about finding a value for one and then use it twice. If you have a square of side length x and you cut 2 squares out of each side measuring 3 inches each, you are cutting away 6 inches. So the side now reflects a length of x - 6. Which is used for the length and the width in our formula. The height of the box will be 3 inches, or in other words, what you cut away from each corner to make a box in the first place! So our formula will look like this: 675 = (x - 6)(x - 6)3. Easiest thing to do is to divide away the 3 to get 225 = (x - 6)(x - 6). Now expand that by FOILing:
225= x^{2} -12x+36
Set it equal to 0 to solve for x, the length and width of each side by moving the 225 over to the other side:
x^{2} -12x-189=0
Now you just have to factor this.  When you do, you get x values of 21 and -9. But we all know that you cannot have a side length be a negative number so the x value is 21.  That's the side length of the original paper before you cut 6 inches away.

Complete the statement to describe the expression (a+b+c)(d+e+f)
Nat2105 [25]

Answer:

Please check the explanation.

Step-by-step explanation:

We know that if we multiply 3 and 4, we get 12.

In other words, 3 × 4 = 12

Thus, 3 and 4 are factors of 12.

now

Given the expression

(a+b+c)(d+e+f)

The given expression consists of two factors which are:

  • (a+b+c)
  • (d+e+f)

We also know that an expression can consist of terms, a term may be a constant or a variable. It can be both as well.

For example, in the expression, 4b + 2, 4b and 2 are terms.

so,

  • The factor (a+b+c) consists of 3 terms. These terms are a, b and c.
  • Similarly, the factor (d+e+f) consists of 3 terms. These terms are d, e, and f.
