Answer:
12
Step-by-step explanation:
AD is 6. a bisector splits a line in half. X would equal 6 meaning AD would equal 12.
7x-8 (2) = 12x+8
14x-16 = 12x+8
-12x -12x
2x-16 = 8
+16 +16
2x = 24
÷2 ÷2
x= 12
UV= 7x-8
UV= 7(12)-8
UV= 84-8
UV= 76
Answer:
f(x) = 12x - 4
Step-by-step explanation:
f(x)= 20 + 12(x - 2)
Distribute
f(x) =20 +12x - 24
Combine like terms
f(x) = 12x+20-24
f(x) = 12x - 4
1 because you replace x with 2 so, (2)squared -5x2 + 7 = 4 - 10 + 7 = 1
