Answer:
15
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(5+x) * 5 = 10^2
Distribute
25 +5x = 100
Subtract 25 from each side
25-25 +5x = 100-25
5x= 75
Divide by 5
5x/5 = 75/5
x = 15
-5.55 - 8.55c + 4.35c
-8.55c + 4.35c = -4.2c
-5.55 - 4.2c is the answer.
There is no distance since they are the same exact number.
Answer:
n=10
Step-by-step explanation:
You need n to be 10 because: y^20= (y^10)^2
Y because if you add them you will get 10x =-10
The y will be eliminated because you have positive 3 -4
