Square roots of negative numbers will have "i"  in them. \(\sqrt{-1}=i\). So the square root of a negative number would be the square root of the number if it were postiive with an i.

The sum of 27 conescutive integers is 3^7 or 2187.

We write an equation x+(x+1)+(x+2)+...(x+26)=2187 and solve for x.

x+(x+1)+(x+2)+...(x+26)=2187

27x+351=2187

27x=1836

x=68.

The median is x+12, so the median is 68+12=80.

The slope intercept equation is in the form y=mx+b. We already know the slope so we have y=-2x+b. Then we plug in the point (-3, 10) to find b, the y-intercept.

y=-2x+b

10=-2(-3)+b

10=6+b

b=4

So the y intercept of line PQ is (0, 4).

The equation for amount of work done is w=rth, where w represents the work done, r the rate, t the time, and h the number of people or things doing work.

So with the first sentence we have 5=r(20)(5), which simplifies to 5=100r, so r=1/20. Now we substitute this into the equation for our second sentence.

9=(1/20)(t)(9)

9=9/20t

t=20 minutes.

um it looks like something's missing from your question. Or is this just a troll post?

Ohh so I just needed to apply this theorem?

Notice that when we divide e into halves and rearrange those halves, the shape is the same as the shaded area. The shaded area is 1/8 of the total square(try dividing the diagram into only the gray area shape). We know the area of the square is 16, and that e is equivalent to 1/8 the area so its area is 1/8 * 16= 2 square inches.
