Answer:
x = ±6i sqrt(2)
Step-by-step explanation:
6x^2 + 432 = 0
Subtract 432 from each side
6x^2 =- 432
Divide by 6
6x^2 /6 =- 432/6
x^2 =-72
Take the square root of each side
sqrt(x^2) = ±sqrt( -72)
x = ±sqrt(-1) sqrt(2*36)
We know the square root of -1 = i
x = ±i sqrt(2*36)
x = ±i sqrt(36) sqrt(2)
x = ±6i sqrt(2)

Answer:
0.7143ans
Step-by-step explanation:
y=1/x
y=k/x
k=yx
given x=3,y=5
k=5×3=15
when y=21
x=k/y
x=15/21=0.7143ans
Perimeter of quarter circle formula =
1/4 x pi x radius + 2r
so 1/4 x 3.142 x 7
= 5.4985
5.4985 + 7 + 7
= 19.4985
≈ 19.50 ( 2 decimal place )
