Answer:
C. (2x – 1)(2x + 1)
Step-by-step explanation:
4x² – 1 = (2x)(2x) – 1 = (2x – 1)(2x + 1)
Answer:
A) $17,332.59
Step-by-step explanation:
$16,000(e^(0.02[or 2%] * 4)) = $16,000(e^0.08)
e^0.08 = 1.08328706767 * $16,000 ≈ $17,332.59
Answer:
x = 12
Step-by-step explanation:
The total of all the angle is 180 degrees so just divide 180 by the total number of x's which is 5+4+3+2+1 = 15
180/15 = 12
If you wanted to know how much each angle is just plug in 12 for x.
So first angle is just X so it is 12 degrees.
Second angle is 2X so 2x12 = 24 degrees.
and so on for all the angles.
Answer:
238°
Step-by-step explanation:
In a cyclic quadrilateral, the pair of opposite angles add up to 180 degrees.
So, the angle "21x - 2" and the angle "38x + 5" add up to 180.
So, we can write an equation and solve for x first:

x = 3
Now, Arc FGH is DOUBLE of Angle A. Angle A is "38x + 5". We know x, so angle A is:
Angle A = 38x + 5 = 38(3) + 5 = 119
Thus, Arc FGH = 2 * 119 = 238°
