Answer:
23 units
Step-by-step explanation:
Since both lines are chords, they're equal in length. This means we can set them equal to each other.
2x + 2x +2 = 15 + 8
This becomes 4x + 2 = 23.
Subtract two from each side to get 4x = 21.
Now divide by 4 to isolate x.
This makes x = 5.25.
Now we take the 5.25 and substitute it into the 2x + 2x + 2. This equals 23 units
144. 3^2 * 4^2. 9 * 16 = 144
-4p+(-2)+2p+3 simplified is:
-2p+1.
Hope this helped.
