4 0

Answer:

B

Step-by-step explanation:

{18}^{2}  =  {x}^{2}  +  {x}^{2} \\  \frac{18 \times 18}{2}  =  {x}^{2}  \\ x =  \sqrt{9 \times 18}  \\ x =  \sqrt{9 \times 9 \times 2}  \\ x = 9 \sqrt{2}

If the difference of two numbers is 43 in the sum of the numbers is 13 what are the numbers
bulgar [2K]
A-b = 43----(1)
a+b = 13----(2)

Matt invested $1500 into a stock of his choice. After two years, he had received
EleoNora [17]

For this question, the time given confuses me.  I know the rate of return is just total return divided by divided by investment, Assuming that Matt received the $400 in dividends as cash payouts, and they weren't reinvested into buying shares of the stock, then his total return over two years was $500, Now, if Matt's dividends were reinvested into the stock - and if you have a 401(k) or IRA, that's what usually happens - then his ROI would have been only 6% because he only made a profit of $100 on an investment of $1500. Note:  In the real world, in current market conditions, Matt probably would have got about a 5% return on a good stock, and Bella would have received about 0.05% on a savings account.

hope this helped you ;)
