Answer: 6

Step-by-step explanation: okay. Here we go. This will be long.

You have to use the inverse operation. That means use the opposite operation. For example, the opposite operation of addition is subtraction. So let’s ignore the 3x for now. That means the equation is +2=20. The inverse operation of addition is subtraction. So we subtract 2 from 20. That equals 18. Then we subtract 2 from 2. That equals 0. Now our equation is =18. Now remember 3x? You bring that back in. So our equation is 3x=18. See what I did? I simplified the equation. 3x means “3 times x” because x is a variable. And the opposite of times (multiplication) is division. So you divide 3 from 18. That equals 6. And we divide 3 from 3x. That equals 1x. Ax is basically the same thing as x. So now what doe we have left? X= 6. Your answer is 6.

??????????????????????????????

You want to find the time <em>t</em> such that

\$1000 = \$200 e^{0.04t}

Divide both sides by $200 :

\dfrac{\$1000}{\$200} = 5 = e^{0.04t}

Take the logarithm of both sides:

\ln(5) = \ln(e^{0.04t}) = 0.04t\ln(e) = 0.04t

Divide both sides by 0.04 and solve for <em>t</em> :

t = \dfrac{\ln(5)}{0.04} \approx 40.24 \approx \boxed{40}

Answer:

-6xy

Step-by-step explanation:

(2x-y)x(x-2y)-(x+2y)X(2x-y)

remove the parentheses

2x^2-4xy+xy-2y^2-(2x^2-xy+4xy-2y^2)

collect terms

2x^2-4xy+xy-2y^2-(2x^2+3xy-2y^2)

remove the parentheses

2x^2-4xy+xy-2y^2-2x^2-3xy+2y^2

remove the opposites, collect the terms to get -6xy
