<h3>Answer: (3, 4) is not a solution if given inequality.</h3>
Answer:
Imara's error will be that she did not find the side lengths of the square with an area of 625.
Step-by-step explanation:
Imara used these steps to find the length of the hypotenuse of the right triangle.
Step 1: Find the area of the square with side lengths of 20 i.e. 400
Step 2: Find the area of the square with side lengths of 15 i.e. 225
Step 3: Find the sum of the areas of the two squares i.e. 625
Step 4: State the length of the hypotenuse i.e. 625
Therefore, Imara's error will be that she did not find the side lengths of the square with an area of 625. (Answer)
The greatest common factor (or GCF) is, as the name says, the greatest factor a set of numbers have in common. We can find this by listing out all the possible factors (multiples) of each number:
For 28:
<u>1</u>, <u>2</u>, 4, <u>7</u>, 14, 28
For 42
<u>1</u>, <u>2</u>, 3, 6, <u>7</u>, 21, 42
<em>(note you don't need to list out all the factors, I just did it for visual purposes)</em>
As you can see, 28 and 42 have 3 factors in common, with 7 being the greatest.
Therefore, the answer would be C: the GCF is 7.

I believe that the answer is A. If you need any help with how to show work I'd be happy to help you in the comments :0 hope this helps!
There is one solution to that system and it is 3, 4
