Answer:
Step-by-step explanation:
This is an geometric series.
Common ratio = second number÷ first number
To get the next number, 256 should be divide by (-4)
The three numbers are : -64 , 16 , -4
The answer is the square root of 4.
2 * 2 = 4
2 is a rational number; therefore, the square root of 4 is a rational number.
2x-7y=18 _(1)
-2x+4y=5
11y=23 , Y=23/11 sub in 1
2x-7×23/11=18
2x = 18×11 + 7×23
x = ( 198 + 161 )/2 = 359/2

Among the choices provided the answer should be letter C. Below is the solution:
top
<span>pi r^2 or pi * 400 </span>
<span>sides </span>
<span>2 pi r * 60 </span>
<span>40 * 60 pi </span>
<span>2400pi </span>
<span>so add the top and side we get p*400 + p*2400 = 2800 pi ft^2</span>
