Your answer should be B. Two sets are equal if they contain the same elements. Two sets are equivalent if they have the same cardinality or the same number of elements.

Which is an equation?<br> a. 17 + x<br> b. 45 / x <br> c. 20x = 200<br> d. 90 - x

eimsori [14]

C. 20x = 200 because an equation always has an equal sign and other three are expressions because it doesn't have any signs, hoped this helped:)

The rectangle below has an area of 6n^4+20n^3+14n^26n 4 +20n 3 +14n 2 6, n, start superscript, 4, end superscript, plus, 20, n,

Sindrei [870]

Given:

Area of rectangle = $6n^4+20n^3+14n^2$

Width of the rectangle is equal to the greatest common monomial factor of $6n^4, 20n^3,14n^2$ .

To find:

Length and width of the rectangle.

Solution:

Width of the rectangle is equal to the greatest common monomial factor of $6n^4, 20n^3,14n^2$ is

$6n^4=2\times 3\times n\times n\times n\times n$

$20n^3=2\times 2\times 5\times n\times n\times n$

$14n^2=2\times 7\times n\times n$

Now,

$GCF(6n^4, 20n^3,14n^2)=2\times n\times n=2n^2$

So, width of the rectangle is $2n^2$ .

Area of rectangle is

$Area=6n^4+20n^3+14n^2$

Taking out GCF, we get

$Area=2n^2(3n^2+10n+7)$

We know that, area of a rectangle is the product of its length and width.

Since, width of the rectangle is $2n^2$ , therefore length of the rectangle is $(3n^2+10n+7)$ .

Which function below is the inverse of f(x)= 7x-1/2

Keith_Richards [23]

Answer: $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$

Step-by-step explanation:

If we have y=7x-1/2, the inverse is where we solve for x instead of y.

We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.

Therefore, $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$ .

Hope that helped,

What is the slope?

ANTONII [103]

Answer:

1/3

Steps:

The line rose 10 values (up) and went 30 values higher (to the right), so you divide 10/30 and end up with 1/3
