Answer:
80%
Step-by-step explanation:
(54-30)/30 *100 = 80%
Answer:
x can have two complex solutions, which are:
-2 + i
-2 - i
Step-by-step explanation:
2x² + 8x + 10 = 0
4x² + 16x + 20 = 0
4x² + 16x + 16 = -4
(2x + 4)² = -4
2x + 4 = √-4
2x = -4 ± i√4
2x = -4 ± 2i
x = -2 ± i
So x is equal to -2 + i and -2 - i.
The angle diagonal to 103° is equal to 103°. So here's your equation:
(103+14x+7)°=180°
So now you can simplify:
110°+14x=180°
now subtract 110 on both sides
14x=70°
now divide by 14 on both sides
so the answer is x=5°
hope this helps
Set like terms on each side by adding six to the first side and subtracting 1/2x from the first side. this gives you 9<1.5x. divide both sides by 1.5 to get 66. the answer is 4) x>6
