In this case we use intersecting secant theorem
According to this theorem, GF*GE = GH*GA
So,we plug in the values
(x-3)*(x-3+9) =(x-2)*(x-2+6)
(x-3)*(x+6) =(x-2)*(x+4)
x^2 +6x -3x -18 =x^2 +4x -2x -8
x^2 +3x -18 =x^2 +2x -8
x^2 +3x -18 -x^2 -2x +8 =0
x -10 =0
x=10
So,FG =x-3 = 10-3 =7
Answer:
(a)
Step-by-step explanation:
Given
4x - 1 = x ( subtract x from both sides )
3x - 1 = 0 ( add 1 to both sides )
3x = 1 ( multiply both sides by 10 )
30x = 10 → (a)

For this case we have the following equation 
, from which we must clear the value of the variable "x" and round to the nearest hundredth. To do this, we must apply properties of neperian and exponential logarithms. By definition:
So:
We apply Neperian logarithm to both sides:
We divide between "3" both sides of the equation:
Rounding out the nearest hundredth we have:
Answer:
just do 2.80-0.75 and you'll get your original which is 2.05 for the 2nd past
for the 1st one I'd do 2.80 divided by 0.75 and I would get 37 cents
