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

Step-by-step explanation:
V=bh
b= 5 x4 h=4
5 x 4 x 4 = 80
The system of equations provides a unique solution(one solution) at (-0.6, 1.6).
<h2>Given to us,</h2>
<h3>Equation 2</h3>
As we already have the value of y from equation 1, substitute its value in equation 2,
<h3>Equation 1,</h3>
substitute the value of x in equation 1,
As we can see the system of equations provides a unique solution(one solution) at (-0.6, 1.6).
