Answer:
-7+26i
Step-by-step explanation:
Use FOIL
2•4+2(3i)+5i•4+5i(3i)
Simplify by combining like terms for your answer
8+6i+20i-15
-7+26i
Answer:
The answer to your question is below
Step-by-step explanation:
A) 2x > -6
x > -6/2
x > -3
It must be a graph with an open circle starting at -3 and then to the right.
It is the first graph.
B) x - 4 < -7
x < -7 + 4
x < -3
The graph must be an open circle starting at -3 and pointing to the left.
it is the second graph.
C) 6 + x ≤ 3
x ≤ -6 + 3
x ≤ -3
The graph must be a closed circle starting at -3 and pointing to the left.
it is the forth graph.
D) -x - 5 ≤ -2
-x ≤ -2 + 5
- x ≤ 3
x ≥ -3
The graph must be a closed circle starting at -3 and pointing to the right.
It is the third graph.
