Answer:
C. 3 (t+2)
Step-by-step explanation:
First, for the top fraction, simplify it:
4(t^2-4)/8=4(t+2)(t-2)/8
Now, flip the denominator and multiply the top and bottom fractions:
4(t+2)(t-2)/8 * 6/t-2
You can cancel the (t-2) terms so you get:
4(t+2) *6/8
Reduce the 6/8 to 3/4 so you get:
4(t+2)*3/4
Now cancel the 4's:
3(t+2) Your answer is C.
Answer:
By power of a point, AC⋅CB=DC⋅CE. That is, 12⋅12=6⋅(2R–6).
Then, R=15.
there are only 3 tangent lines can be drawn that touch both circles
ok done. Thank to me :>
Answer:
x = 4
Step-by-step explanation:
3x + x + (x + 3) = 23 feet
3x + x + x = 20 feet
5x = 20 feet
x = 20/5
x = 4
