Answer:
Step-by-step explanation:
The area of the swimming pool will be equal to 
.
We know that the length is 
and the width is 
.
Therefore we can substitute those into the equation:
Then, we expand the brackets using a grid (attached).
After this, we collect like terms to find the final answer:
Our final answer is:
Answer:
40 weeks
Step-by-step explanation:
You can use the fact that there are 52 weeks in a year. If she attends school for 3/4 the year, find out what 3/4 of 52 is, and then add 1:
52/1 * 3/4 = 156/4 = 39 This is 3/4 year
39 + 1 = 40
Answer:
B
Step-by-step explanation:
1. In order to determine the inequality, you must first solve the solution set to determine what x is less than.
So you would do this:
1 + 2x < 9 Subtract 1
2x < 8 Divide by 2
x < 4
2. Next, you need to understand the difference between an open circle and a closed circle shown on the solution sets.
An open circle is equal to the following inequalities:
<, >
A Closed circle represents inequalities in situations such as:
greater than or equal to, or less than or equal to
3. Because the inequality above represents only less than or greater than the inequality sets should have an open circle being used.
Since x is less than 4 it should be moving to the left of the line inequality set.
