Answer:
x = 4i - 1 or
x = 4i + 1
Step-by-step explanation:
(x+1)^2 = -4
x+1 = (+-)4i
x = +-4i - 1
==>
x = 4i - 1 or
x = 4i + 1
Answer:
Area:50.24 Perimeter: 25.12
Step-by-step explanation:
Do find area you have to divide 8 by 2 which is 4 and thats the radius and then you do pi(3.14) times 4 squared and thats means multiply 4 times itself and that fives you 16 times pi(3.14) and the answer for area is 50.24
Second thing is the circumference is the same as the perimeter so you do pi(3.14) times the diameter 8 and you get 25.12.
Answer:
(-0.3)^4 = 0.0081
Step-by-step explanation:
Answer: x^2+12=x+4
Step-by-step explanation:
Presumably we're supposed to put y in the table. That's not totally clear.
x - 6y = -6
-6y = -x - 6
y = (x+6)/6
x - 3y = -4
-3y = -x - 4
y = (x+4)/3
We wrote them like that because they're a little easier to compute that way.
x y = (x+6)/6 y = (x+4)/3
-4 (-4 + 6)/6 = 2/6 = 1/3 y=(-4+4)/3 = 0
-2 y = (-2+6)/6=2/3 y=(-2+4)/3 =2/3
0 y = (0 + 6)/6 = 1 y=4/3
2 y = 8/6=4/3 y=(2+4)/3=2
4 (4+6)/6=10/6=5/3 y=(4+4)/3=8/3
