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

Answer:
9 × c or 9c
Step-by-step explanation:
Product means multiplication so the answer would be 9 × c. Since there is a variable, the answer doesn't even need the multiplication sign, but it is fine either way.
Answer:
LM = 6
Step-by-step explanation:
use the ratio of corresponding sides
1/3 = 2/LM
LM = 6
