The letters in the equation
Answer:
The expression which will result in difference of two squares is:
(–7x + 4)·(–7x – 4)
Step-by-step explanation:
We know that the formula of the type:
(a-b)(a+b)=a²-b²
i.e. it is a difference of two square quantities. (a^2 and b^2)
since,
a= -7x , b=4
(-7x+4)(-7x-4)= (-7x)² - (4)²
=(7x)² - 4²
So the expression is a difference of two square quantities:
(7x)² and (4)²
Hence the answer is (–7x + 4)·(–7x – 4)....

Answer:
B
Step-by-step explanation:
I believe that the answer to this question is B. I think this because I took 5.2 and divided it by 0.4 which gave me 13. I did 5.2 divided by 0.4 because it wanted to know how many times 0.4 goes into 5.2.
I hope this helps I am rlly srry if I am wrong. have a beautiful day.
