Answer:

Ok so i hope this helps you.

There are 56 dogs when the number of cats is 140.

Step-by-step explanation:

The ratio of dogs to cats:

\frac{2}{5}

The other proportion:

\frac{x}{140}

\frac{2}{5} = \frac{x}{140}

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1

\frac{2}{5} * \frac{28}{28} = \frac{56}{140}

There are 56 dogs when the number of cats is 140.

Rearrange the formula A = \pi r ^ ( 2) for r
tatyana61 [14]
Consider re-writing this formula as "A = pi*r^2."  The backslash symbol "\" is unnecessary.

If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:

A/pi = r^2

Taking the square root of both sides,   sqrt(A/pi) = r (r must be positive in this situation).

Find the product (8/6n-4)(9n^2-4)
Leokris [45]

Answer:

4(3n+2) or 12n+8

Step-by-step explanation:

Given expression is:

(\frac{8}{6n-4})(9n^{2}-4)

The numerator of the fraction will be multiplied with 9n^2- 4

So, Multiplication will give us:

=\frac{8(9n^2-4)}{6n-4}

We can simplify the expression before multiplication.

The numerator will be broken down using the formula:

a^2 - b^2 = (a+b)(a-b)\\So,\\= \frac{8[(3n)^2 - (2)^2]}{6n-4}\\ = \frac{8(3n-2)(3n+2)}{6n-4}

We can take 2 as common factor from denominator

=\frac{8(3n-2)(3n+2)}{2(3n-2)}\\After\ cutting\\= 4(3n+2)

Hence the product is 4(3n+2) or 12n+8 ..
