Answer:
The product is the difference of squares is 
Step-by-step explanation:
Explanation
- The given expression is (m-7)(m+7).
- We have to multiply the given expression.
- Square the first term m. Square the last term 7 .

You can either convert -3 into a fraction, or convert -2/5 into a decimal so you can solve this.
If you decide to convert -3, into a fraction, it would be -3/1, and you'd have to multiply that by the reciprocal of -2/5.
So, you'd have -3/1(-5/2)=15/2, which can be simplified to 7 1/2.
If you decide to convert -2/5 into a decimal, you would get -0.4. You would then divide -3 by -0.4, which is equal to 7.5.
Both 7.5 and 7 1/2 are correct answers, and if you were to convert 7.5 into a fraction and 7 1/2 into a decimal, you would notice that they are the same number, but in different forms.
From the info i'm getting, the best answer is ought to be B, because of increase in the denominator & it's numerator! It keeps the same pace as 1/4.
I do recommend to double check this with a classmate!
If not B, then my best guess is A.
its the first one because you would have 3 left over.
