Answer:
Radius, r, is 3.75
Step-by-step explanation:
From the given diagram,
AB = 9
AC = 6 + r
BC = r
Thus applying the Pythagoras theorem, we have;
= 
+ 
= 
+ 
36 + 12r + = 81 +
collecting like terms,
12r = 81 - 36
12r = 45
r = 
= 3.75
r = 3.75
The radius is 3.75.
Answer:
5x^2+4x=3
Step-by-step explanation:
You add the like terms: 3x^2 and 2x^2, you get 5x^2. You can't do anything else because there are no more terms that are alike.
So the answer would be 5x^+4x=3
Answer:
x = 24
Step-by-step explanation:
9*3 = 27
27 - 3 = 24
x = 24
The answer is 5100 seconds in 85 minutes
