Answer: Choice D. 4x^2 + 20x + 25</h3>
===============================================
Explanation:
Perfect square trinomials are in the form (a+b)^2 = a^2+2ab+b^2
So the first and last terms must be perfect squares. The middle term is twice that of the square roots of each first and last term.
Choice D fits the description because 4x^2 = (2x)^2 is the first term, so a = 2x and 25 = 5^2 is the last term meaning b = 5. Note how 2ab = 2*2x*5 = 20x is the middle term.
-------------
(a+b)^2 = a^2+2ab+b^2
(2x+5)^2 = (2x)^2+2*2x*5+5^2
(2x+5)^2 = 4x^2 + 20x + 25
Well you know how many shirts are sold in two days. so first find out how many in one. so....... 12/2 is 6 so the store sells 6 per day. Multiply this number by 8 to get 48!
Well make sure you work on your math skills..... i love math and i love helping so i'm helping you :) have a blessed day
