Answer:

A) The width is 12 cm; the average time is 3 minutes

Step-by-step explanation:

$\frac{5}{3}= \frac{20}{y}$

Cross multiply.

5 × y = 3 × 20

5y = 60

5y ÷ 5 = 60 ÷ 5

y = 12

The width is 12 cm. Moving onto the time.

$\frac{12}{4} =\frac{y}{1}$

Cross multiply.

4 × y = 12 × 1

4y = 12

4y ÷ 4 = 12 ÷ 4

y = 3

The time is 3 minutes.

Select the expression that is equivalent to the given polynomial.

lesantik [10]

Observe that $16r^4$ is the square of $4r^2$ , and 625 is the square of 25.

So, your expression is a difference of squares, and as such we can rewrite it as

$16r^4-625=(4r^2+25)(4r^2-25)$

Now again, $4r^2$ is the square of $2r$ , and 25 is the square of 5. So, we have a sum and a difference of squares.

But if we think of 25 as $-(5i)^2$ , we have again the difference of two squares, so we have

$4r^2+25=(2r+5i)(2r-5i)$

$4r^2-25=(2r+5)(2r-5)$
