Answer:
1-7i
Step-by-step explanation:
Multiply the parenthesis
-3-4i-3i-4i²
By Definition i²=-1
-3-4i-3i-4 x (-1)
Any expression multiplied by -1 equals its opposite
-3-4i-3i+4
Calculate the sum
1-4i-3i
Collect like terms
1-7i
Since adjacent angles in a parallelogram are supplementary (they add up to 180°), and ∠B is double as ∠A, you have this equation:
∠A + 2·∠A = 180°
From that you can find: 3·∠A = 180° ⇒ ∠A = 60°.
Answer:
the number is -42
Step-by-step explanation:
quotient of a number and 6: x/6
8 more then the quotient of a number and 6 is 1: x/6 + 8= 1
subtract 8 from both sides
x/6 = -7
multiply both sides by 6 to isolate x
x=-7 times 6= -42.
