Given:

The volume V(x) in cubic inches of this type of  open-top box is a function of the side length x in inches of the square cutouts and can be given by

V(x)=(17-2x)(11-2x)(x)

To find:

The above equation by expanding the  polynomial.

Solution:

We have,

V(x)=(17-2x)(11-2x)(x)

Using distributive property, we get

V(x)=[17(11-2x)-2x(11-2x)](x)

V(x)=[17(11)+17(-2x)-2x(11)-2x(-2x)](x)

V(x)=[187-34x-22x+4x^2](x)

Combining likes terms, we get

V(x)=[187-56x+4x^2](x)

Using distributive property, we get

V(x)=187x-56x^2+4x^3

V(x)=4x^3-56x^2+187x

Therefore, the required equation after expanding the  polynomial is V(x)=4x^3-56x^2+187x.

Answer: If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.

Step-by-step explanation:

If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.

A contrapositive statement is when you take the original statement, "flip" it around, and write the opposite of the original statement. Here's an example:

<u>Original statement:</u> The grass is wet because it was raining.

<u>Contrapositive statement:</u> It was not raining, so the grass is not wet.

Notice how we "flipped" the original sentence around, as wrote it's "opposite".

All you have to do is substitute the y value from the 1st equation into the second equation and solve...

a) y= 2-x
5x + 4y = 5

Substitute (2-x) into the second equation anywhere there is a y...

5x + 4y = 5
5x + 4(2-x) = 5

Now solve

5x + 8 - 4x = 5
5x - 4x + 8 = 5
x + 8 = 5
x = -3

Now that you have a solution for x, substitute -3 into either of the original equations anywhere there is an x then solve for y...

y = 2 - x
y = 2 - (-3)
y = 2+3 = 5

You solved for x and got -3 and solved for y and got 5, so your solution set is
(-3, 5).

Now check it by substituting both numbers into one of the original equations and you should have a true statement if it is correct...

y = 2 - x
5 = 2 - (-3)
5 = 2+3
5 = 5

True statement... it checks!


note* during the check, if the equation would have worked out to something like 2 = 5, then that is a false statement therefore the solution set would be wrong and you'd have to go back and find the mistake.
