Need with this. can you tell me the answer to this?

(5+x)(5-x)

Step-by-step explanation:

5^2-x^2, simplified.

Difference of squares formula= a^2-b^2=(a+b)(a-b)

5^2-x^2=(5+x)(5-x).

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
