Answer answer is A,D,B,D,C
Domain is all the x's
and range is all the y's
so domain is {1, 2, 3, 4}
and range is {2, 7, 12, 17}
I think its B because it is always B
Answer:
D
Step-by-step explanation:
When you add all the the angles of a triangle, they will end up to be exactly 180 degree. When you add the three numbers A, B, and C end up with 180 degree, but D end up with 130 degree, therefore, D is the triangle that cannot exist.
Hope it helps :D
(2-5i)(4+7i)=2(4+7i)-5i(4+7i)=8+14i-20i-35i²
recall that i²=-1,
8-6i+35=43-6i
43-6i is the final answer
