Answer:
See below.
Step-by-step explanation:
Total = 110
Let calls on third evening = x
second evening = 4x
first evening = x + 8
=> x + 4x + x + 8 = 110
=> 6x = 102
=> x = 17
First evening = x = 17 calls
Second evening = 4x = 68 calls
Third evening = x + 8 = 25 calls
Area of a square: s^2
Because we know the length of one side, we can multiply it by itself to find the area.
(3x - 6)(3x - 6)
9x^2 - 18x - 18x + 36
Combine like terms.
9x^2 - 36x + 36
<h3>The correct answer is A, or the first answer. </h3>
Here is 974 in expanded form
900+70+4 =974
Answer: 59
explanation: PEMDAS, first multiply 9x6 as they are multiplication then add

The measure of the Central Angle indicated is; 45°
<h3>How to find the central angle of a circle?</h3>
The central angle will be the angle subtended at the center by arc FE and arc CB.
Now, we see that angle ∠FOB = 135° and since we know that sum of angles on a straight line is 180°, then we can say that;
Central Angle = 180° - 135° = 45°
Angle subtended by Arc CD at the center is;
θ = 180 - (81 + 45)
θ = 54°
