Answer:
X = 4
Step-by-step explanation:
Step-by-step explanation:
When a = -1 and b = 9,
3a² / (a + b)^(1/3)
= 3(-1)² / [(-1) + 9]^(1/3)
= 3 / (8)^(1/3)
= 3 / 2
= 1.5.
We hates fractions, yess precious, nasty fracitons
multiply both sides by (x-2)(x+1) to clea fractions
x(x+1)+(x-1)(x-2)=(-1)(x-2)(x+1)
distribute
x^2+x+x^2-3x+2=-x^2+x-2
add like terms
2x^2-2x+2=-x^2+x+2
add x^2 to both sdes
3x^2-2x+2=x+2
minus x from both sides
3x^2-3x+2=2
minus 2 both sides
3x^2-3x=0
factor
(3x)(x-1)=0
set to zero
3x=0
x=0
x-1=0
x=1
x=0 or 1
Answer:
6
Step-by-step explanation:
A circle is 360 degrees
The central angle is 120 degrees
120/360 = 1/3
The arc is 1/3 of the circle or 1/3 of the circumference
1/3 * 18 = 6
