The area of a square is found by squaring one of its sides, (A = s2). A certain square has an area of z2 + 18z + 81. Factor the
trinomial to find a side of the square.
side = z + 27
side = z + 18
side = z + 9
2 answers:
Here is your answer
Given area is
z^2 + 18z + 81
= z^2 + 2× z × 9 + 9^2
[using (a+b)^2= a^2 + 2ab + b^2], we get
= (z+9)^2
we know that area of a square is represented by side^2.
So, here
Side of square is

Answer:
(-3,0) = x and (0,4) = y
Step-by-step explanation:
In triangle the sum of the angles =180,and we have angle=124 so,180-124=56.
