Answer:
I think A but i'm not sure
Line segment AD is 4cm. Because A is the center, any lines coming off the centerpoint are congruent. So if line AC is 4cm, then line AD has to be 4cm as well.
Answer:
42
Step-by-step explanation:
-4(7a+5)= —160
distribute the -4 on the left hand side
-4* 7a + -4*5 = -160
-28a +-20 = 160
-28a -20 = -160
add 20 to each side
-28a-20+20 = -160 +20
-28a = -140
divide by -28 on each side
-28a/-28 = -140/-28
a = 5
Answer: a=5
