2(2)-3-2+4=3 which is 4-3-2+4=3 which is -1+4=3 which is 3=3 which is correct.

Hope this helps :)

Answer:

Step-by-step explanation:

$\bigg( \frac{16}{49} \bigg)^{ - \frac{3}{2} } \\ \\ = \bigg( \frac{49}{16} \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}^{2} }{ {4}^{2} } \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ \frac{2 \times 3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ 3} \\ \\ = \frac{343}{64} \\$

So.

Let's get started with formulas.
.
I KNOW you hate formulas!! So do I, but we have to use them. No "buts".
.
So, how many minutes are in 2 weeks?
.
Search it up. For your convenience, it is 20,160 minutes.
.
Well, I think you have your answer, since each quiz is 5 minutes, 5 times 50 (5 x 50) is 2,500 minutes.
.
Yes, you can do 50 quizzes and MUCH MUCH more in 2 weeks.

Hope I helped!!

Answer please, thanks.

A) The perimeter is the length around the rectangle, so it would be 2 + 5 + 2 + 5 = 14m

The area is 2m * 5m = 10m^2

b/c) You have to draw a rectangle with a perimeter of 14m, and an area that ISN'T 10m^2. You could draw a 3m by 4m rectangle which would have a perimeter of 14m and an area of 12m^2.
