The product of (a + b)(a − b) is a perfect square trinomial. (1 point) a
Sometimes

b
Always

c
Never

Step-by-step explanation:

step 1. (a + b)(a - b) = a^2 - ab + ab - b^2 = a^2 - b^2.

step 2. this is always a binomial and never a trinomial and hence never a perfect square trinomual.

step 3. never.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
