**Answer:**

**Step-by-step explanation:**

1. 4×30×20=2400f²

2. 2400÷300=8

3. 8 gallons

**Answer:**

7,8,9

**Step-by-step explanation:**

let the integers be n,n+1,n+2

According to the question,

n+n+1+n+2=24

or,3n+3=24

or,3n=21

or,n=7

So,the consecutive integers are n+1=8 and n+2=9

If PQRS is a rhombus,** then the opposite sides must be parallel to each other. **

good luck :)

In this case, the parenthesis do not matter. the value of the equation remains the same with or without them. so you can rewrite this as y + 1 + 4, which is y + 5.
