Which expressions are differences of squares?

choose all answers that are correct.

8b^2 - 16c^6

16e^8 - 81g^4

49x^25 - 4y16

121m^18 - 9n^10

Step-by-step explanation:

For a term to be a square, the coefficient must be a square (8 is not), and the degree must be even (25 is not). Of course, the sign between the terms must be a minus sign.

After eliminating the expressions that don't contain squares, the remaining expressions are listed above.

16e^8-81g^4    and   121m^18-9n^10

idk

step-by-step explanation: i just don't

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
