have a nice day
The answer is 11 i
<em /><em>Explanation:
</em>
The square root needs to be a number that can be multiplied by itself and equal the original number.
In this case, the number is 11, 11*11 = 121
However, you are looking for the square root of a negative number, due to this you would add i to the answer,
i = imaginary number, or -
( Depending on your grade/ teacher however, you can put "no solution"

<h2>
Step-by-step explanation:</h2>
<em>(Solving for x on question - 2x + 3y = 32)</em>
2x + 3y = 32
Step 1: Add -3y to both sides.
2x + 3y + −3y = 32 + −3y
2x = −3y + 32
Step 2: Divide both sides by 2.
= ![\frac{-3y+32}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-3y%2B32%7D%7B2%7D)
<u>x = </u>
<u>⁻y + 16</u><u> </u>
<em>(Solving for y on question - 2x + 3y = 32)</em>
2x + 3y = 32
Step 1: Add -2x to both sides.
2x + 3y + −2x = 32+ −2x
3y = −2x + 32
Step 2: Divide both sides by 3.
= ![\frac{-2x+32}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-2x%2B32%7D%7B3%7D)
<u>y = </u>
<u>x + </u>
<u> </u>
<em>(Solving for x on question - 5x - 4y = -81)</em>
5x − 4y = −81
Step 1: Add 4y to both sides.
5x − 4y + 4y = −81 + 4y
5x = 4y − 81
Step 2: Divide both sides by 5.
=
<u>x = </u>
<u>y + </u>
<u> </u>
<em>(Solving for y on question - 5x - 4y = -81 )</em>
5x − 4y = −81
Step 1: Add -5x to both sides.
5x − 4y + −5x = −81 + −5x
−4y = −5x − 81
Step 2: Divide both sides by -4.

Answer:
5.50 years
Step-by-step explanation:
A = P![(1 + \frac{r}{n})^{nt}](https://tex.z-dn.net/?f=%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
3178 = 2000(1+.086/2)^2t
t = 5.499904413
