First, simplify the denominator into 1+3i. Then multiply both the numerator and denominator by 1-3i to rationalize the denominator. Then, the numerator becomes i+3, and the denominator becomes 10. So, the first answer is correct.

Jet001 [13]
For with the careless bones of the young men harvested by the night and bindled around campfires were the similarly strewn steel bones of their rifle, with bayonets fixed like eternal lightning lost in the orchard grass.

The length of a rectangle is twice the width. The area is 162 yd? Find the length and the width.
Tresset [83]

Answer:

length = 2x = 2(9) = 18 yds

Step-by-step explanation:

Let width = x

Let length = 2x

Area = 162 yd2

 

length × width = Area

 

2x(x) = 162

2x2 = 162

 

Divide by 2 on both sides of equation.

 

x2 = 81

 

Square-root both sides of equation to undo the exponent.

 

x = √(81)

x = 9

 

Substitute this x value into the initial variables.

 

width = x = 9 yds

length = 2x = 2(9) = 18 yds
