The value of 
Step-by-step explanation:
Being the general expression of the sequence:

We replace the value n=12 to get

The multiple of 3 and 100 is 33
Answer:
x = 16
Step-by-step explanation:
(x +4) : (x +12) :: (x-1)(x +5)
As they are in proportion,
Product of means = Product of extremes
(x + 4)* (x +5) = (x + 12)(x - 1) {Use FOIL method}
x*x +x*5 +4*x + 4*5 = x *x + x*(-1) +12*x + 12*(-1)
x² + <u>5x + 4x</u> + 20 = x² <u>- x +12x</u> - 12 {Now combine like terms}
x² + 9x + 20 = x² + 11x -12
x² + 9x +20 - x² - 11x = -12
x² - x² + 9x - 11x = -12 - 20
0 - 2x = - 32
-2x = -32 {Divide both sides by -2}
x = -32/-2
x = 16
Answer: the measure of angle 1 is 55 degrees
Step-by-step explanation:
so you see the outside of 5 is 125 degrees on the right side? So that 125 is equal to the 5 on the other side. So to find measure 1 you need to figure out the measure of the rest of the outside which is the outer angle of measure 1.
So you do
125+125=250
and then,
360-250=110
and since measure of angle 1 starts at the edge of the angle and not the center, you do 110/2 which is 55.
IF THE ANGLE OF MEASURE 1 WAS FROM THE CENTER POINT TO THE END <u>DO NOT </u>DIVIDE BY TWO.
