Answer: it d mabe
Step-by-step explanation:
The 30 units line is the midpoint of the two sides it’s joining(as it cuts both as 21,21 and 44,44)
Therefore we can use midpoint theorem to say that x = 60 ( the line joining the midpoints of two lines is parallel and half of the third line in a triangle)
Answer:
no it has to be the same length
Step-by-step explanation:
it has to be the same
Answer:
c
Step-by-step explanation:
Given the roots are x = - 1 + 4i and x = - 1 - 4i then the factors are
(x - (- 1 + 4i))(x - (- 1 - 4i))
= (x + 1- 4i )(x + 1 + 4i )
= (x + 1)² - 16i² → [ i² = - 1 ]
Expand and simplify
= x² + 2x + 1 + 16
Hence
x² + 2x + 17 = 0 → c
