Answer:
If the area of a square is given by the polynomial 4x2 – 36x + 81, then which of the
following expressions represents the length of one side of the square?
A 2x -9
B
2x + 9
C 4x - 18
D 4x + 18
Step-by-step explanation:
answer 4x+18
The outside angle of B needs to equal 180 - 79 = 101 degrees.
The 3 outside angles of a triangle need to equal 360 degrees.
Set up the equation with what we know:
X + (x+5) + 101 = 360
Simplify:
2x + 106 = 360
Subtract 106 from both sides:
2x = 254
Divide both sides by 2:
x = 254 / 2
x = 127
Given A = {a, e, i, o, u} and B = {a, l, g, e, b, r}, find A ∪ B.

Ahh..this is sets topics - A U B = all the elements found in A and B. But do note, do not repeat the elements if it is the same. And if the question were to ask : n(AUB) = total number of elements found in A and B.
7,265 is the average of those two numbers, though i am not sure what the sign that is mentioned is
