Answer:
graphhhhhh
Step-by-step explanation:
The slope is -3/4 so you up 3, left 4. or down 3, right 4.
You start at 1 on the y axis and then do this^.
Then you look at the line you have made and see which points are obvious.
You can just copy what I got on the graph below.
The base is 15 ft.
Using the formula A=bh, we substitute the information we have. We know the area and the height:
127.5 = b(8.5)
Divide both sides by 8.5:
127.5/8.5 = b(8.5)/8.5
15 = b
The base is 15.
<u>Answer:</u>

We can use the following rule of surds to solve the problem:
,
which means that when multiplying two numbers with the same bases, we can simply add their powers while keeping the base the same.
Applying this rule:
