Answer:
12 and 4
Step-by-step explanation:
We could set up two equations with the given information.
Let a be the larger number, and b be the smaller number.
4b - 4 = a (Four subtracted from four times the smaller is equal to the larger number.)
2a = 6b (Twice the larger number equals six times the smaller number.)
With the 1st equation, we could substitute a = 4b - 4 into the second equation.
We get
2(4b-4) = 6b
8b - 8 = 6b
2b = 8
b = 4
Substituting back into the first equation,
a = 4(4) - 4 = 12
Therefore the two numbers are 12 and 4.

Answer:
15.5
Step-by-step explanation:
So the formula here is the square of the tangent length is equal to the product of the exterior part of the secant line and total length of the secant.
So that means we have x^2=10(14+10).
After simplifying the right hand side we have the equation is x^2=10(24) or x^2=240.
To get rid of the square on the x, we square root both sides.
x=sqrt(240)
x=15.49193338
To the nearest tenths, the answer is x=15.5
So 15.5 inches is the length of x.
