For 13. just add all the sides.

4 + 21 + 23 + 7 + 9 = 64

For 14. multiply width and height of both shapes then add them together.

1.7 x 5.2 = 3.74 ( rectangle area )
3.0 x 3.0 divided by 2 = 4.5 ( triangle area )

Add the two answers

3.74 + 4.5 = 8.24

Question 4 pleaseeeeeee
arsen [322]

Answer:

B

Step-by-step explanation:

Unit rate means one quantity in terms of another unit quantity. In the answer choices, we see that the denominator is always in terms of UNIT LITERS (1 L), so that means, we have to find gallons in terms of UNIT LITERS.

It means, we have to divide gallons by liters to get in terms of unitary liters.

Let's check the first line:

19.5/75 = 0.26 Gallons / 1 Liter

Now, checking 2nd:

39/150 = 0.26 Gallons / 1 Liter

So, yes, they are the same and other 2 lines would be the same as well. The unit rate is:

0.26 gal/1L

That's answer choice B
