The answer is **C.** To solve for change in velocity you must do final - initial, so 23 - 20, then you can plug it into the acceleration formula with time and solve. You end up with the units miles/hours^2 because the units of time are multiplied together.

**Answer:**

We know that,

**<u>Area of parallelogram (||gm) = b × h</u>**

- 3/4 × h = 21/2
- h = 21/2 - 3/4
- h = 42 - 3/4
- h =
**39/4in**

<u>Hence, the height of parallelogram is **9¾in**</u>.

**Answer:**

grams

**Step-by-step explanation:**

kilometers is for length, milugrams are too small and millimeters dosent make sense

Let s be the length of a section for plants.

Because opposite sides in a rectangle are equal we can state that 7 + 5s = 4 + 6s

Subtract 5s and 4 from both sides to get 7 - 4 = 6s - 5s which simplifies to 3 = s

The length of the wall = 7 + 5 x 3 = 22 ft

Check on opposite side: 4 + 6 x 3 = 22 ft
