-(x+1)^2-4=0
2 answers:
Answer:
Step-by-step explanation:
- -(x+1)²- 4 = 0
- (x+1)² = - 4
- x + 1 = ± √-4
- x = -1 ± 2i
Correct choice is D
Answer:
D
Step-by-step explanation:
Given
- (x + 1)² - 4 = 0 ( add 4 to both sides )
- (x + 1)² = 4 ( multiply both sides by - 1 )
(x + 1)² = - 4 ( take the square root of both sides )
x + 1 = ± 
= ± 2i ( subtract 1 from both sides )
x = - 1 ± 2i , then
x = - 1 + 2i, x = - 1 - 2i → D

The savings is the amount taken off or 32% of 150
32% of 150 is 0.32 times 150=48
savings is $48
or you can do
150/100=x/32
cross multiply to get
x=48
so savings is $48
Answer:
6.7
Step-by-step explanation:
60$-37.45=22.55
22.55/3.35=6.731
Which rounds to 6.7
Circumference is Diameter * 3.14
so D * 3.14 = 31.4
31.4 / 3.14 = 10 so the diameter is 10.
the radius is half of the diameter so radius = 5 centimeters.
