Answer:
a. contrapositive because it's the converse and inverse. True.
b. converse because it's the reverse of conditional statement. True.
c. That is false so it's not converse, inverse, or contrapositive.

this is the answer, its pretty simple. I'm not sure the mathematical procedures but if you plug in 7 you get 49. Then all you got to do is subtract by 7, because the question states the number is the same. So basically,
169=13
144=12
Hope this helps and please give brainliest!
Answer:
x = ± 8i/11
Step-by-step explanation:
121x2+64=0
121x^2 = -64
x^2 = -64/121
x = +/- √(-64/121)
x = +/- 8i/11
