What is the first step to solving a system of linear equations algebraically?
Answer:
D
Step-by-step explanation:
as x increases by 1, y increases by 35
You can add the numbers together so:
12.6
3.1
<u>+ 5.4
</u> 21.1
<u>
</u>Since the sum of the numbers is 21.1, it is greater than 20<u>
</u>
I'm 87% sure the answer is B
First, find the area of each figure. Then subtract the smaller area from the larger area. Your work should look something like this:
A = l * w
A = 9 * 9
A = 81
This is the area of the smaller square. Now find the area of the larger square.
A = l * w
A = 15 * 15
A = 225
Now subtract the two areas to find the area of the shape that is left when the smaller square is cut out.
225 - 81 = 144
Your final answer should be:
144 in^2
