Answer:

$x1 = 2 \\ x2 = - \frac{3}{2}$

Step-by-step explanation:

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{1 + - \sqrt{ {( - 1)}^{2} - 4(2)( - 6) } }{2(2)} \\ x = \frac{1 + - \sqrt{1 + 48} }{4} \\ x = \frac{1 + - \sqrt{49} }{4} \\ x = \frac{1 + - 7}{4} \\ \\ x1 = \frac{1 + 7}{4} = \frac{8}{4} = 2 \\ x2 = \frac{1 - 7}{4} = - \frac{6 }{4} = - \frac{3}{2}$

Answer:

r = 6 in

Step-by-step explanation:

$V = \pi r^{2} \frac{h}{3}$ = $216\pi$

r²h/3 = 216

r² (18/3) = 6 r² = 216

r² = 216/6 = 36

Without dividing or listing multiples how can you tell if 61 is a multiple of 6.

Ostrovityanka [42]

For a number to be a multiple of 6, it must be divisible by 6
and a number divisble by 6 means that it is divisble by 2 and 3

since the ones digit is odd it is not divisble by 2 which means 61 is not a multiple of 6

x = -18/48
x = - 3/8 <== ur number
