Answer: option 3. 24m

Step-by-step explanation:

concept to know: (a+b)²=a²+2ab+b²  

                             (a-b)²=a²-2ab+b²

 (2m+3)²-(2m-3)²

=(4m²+12m+9)-(4m²-12m+9) ⇔ Use the formula mentioned above

=4m²+12m+9-4m²+12m-9 ⇔ take off parentheses

=4m²-4m²+12m+12m+9-9 ⇔ move the like term together

=24m ⇔ combine like term

Hope this helps!! :)

Sally has only nickels and dimes in her money box. She knows that she has less than $20 in the box. Let x represent the number o
Mashutka [201]
<span>If  x represent the number of nickels in the box and y represent the number of dimes in the box (note that x>0 and y>0), then the total value of x nickels is $5x and total value of y dimes is $10y. Adding these amounts of money  you get that  in money box was $</span><span><span>(5x+10y)</span>.</span>
<span> Sally knows that she has less than $20 in the box, then 5x+10y<2000 ($20=2000 cents).
</span>
Since this inequality is strict, then you should draw the dashed line 5x+10y=2000. The line divides coordinate plane into two parts.

Pick point (0,0) and consider to which part this point belongs. Since  5·0+10·0<2000, you can conclude that (0,0) is a solution of given inequality and belongs to needed part. Hence you should take the shaded part below the line for positive values of x and y.
