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.

0.48
Step-by-step explanation:
Just move back one decimal point of 4.8
Answer:
7 times x
Step-by-step explanation:
When the expression is seen, we can say that it displays 7 times x.
The answer is D welcome I just knew it In my brain
Answer:
B.
Step-by-step explanation:
Since the numbers in the root is all the same, lets say 
is a variable.
7x - 4 + x
Group with like terms:
7x + x - 4
Combine like terms:
8x - 4
There you have it! Since all the square roots are the same thing, we can treat them like variables.
