</span><span> 5 • (4x - 5) - 155 = 0
</span>  Pull out like factors :
20x - 180  =   20 • (x - 9)<span> 
</span> 20 • (x - 9) = 0  Solve :   <span> 20   =  0
</span>Solve  :    x-9 = 0<span>

Solve for x.<br> -x/3=2<br><br> x= -6<br> x= -1<br> x = 6
LenKa [72]

Answer:

x = -6

Step-by-step explanation:

Solve for x:

-x/3 = 2

Multiply both sides of -x/3 = 2 by -3:

(-3 (-x))/3 = -3×2

-3×(-1)/3 = (-3 (-1))/3:

(-3 (-1))/3 x = -3×2

(-3)/3 = (3 (-1))/3 = -1:

--1 x = -3×2

(-1)^2 = 1:

x = -3×2

-3×2 = -6:

Answer:  x = -6

A cylindrical grain bin has a radius of 7 feet and a height of 25 feet. How many cubic feet of grain can the bin hold
dimaraw [331]

Answer:

1225π

Step-by-step explanation:

The question concerns the volume of the cylinder.

The formula of the volume is:

V=\pi r^{2} h, where r is the radius and h is the height.

Plugging the given numbers into the formula, we find that:

V=\pi * 49 * 25=1225\pi

The result - 1225π shows that the cylinder can be filled fully with that given amount.

Which of the following is equivalent to the complex number i^17
Anton [14]

Answer:

Step-by-step explanation:

It’s a repeating pattern.

i² = -1

i³ =(i²)i = (-1)i = -i

i⁴ = i³i = -i² = 1

i⁵ = (i⁴)i = (1)i = i

i⁶ = i⁵i = i² = -1

...

i¹⁷ = i
