In order to complete the square with the numbers that you have, you would have to add 12.25 to both sides.

In order to complete the square, you always have to add half of the x coefficient squared. Since the x coefficient is 7, we take half of that (3.5) and square it to get 12.25.

Mary, who is sixteen years old, is four times as old as her brother. How old will Mary be when she is twice as old as her brothe
Makovka662 [10]
M = 16
16 = 4B
B = 4
(M - B) = 12  <== this will never change.  Mary will always be 12 yrs older than he is.

So, when she is twice as old as he is, he is 12 and <u>she is 24</u>.
That will occur in 8 years from now.
They should live long and prosper.

Samantha is using a 2-liter pitcher to serve lemonade to 10 of her friends. How many times will she need to fill the pitcher in
Mice21 [21]

Answer: 2 times

Step-by-step explanation:

Hi, since 1000 milliliters = 1 liter

We have to convert the 2 liters into milliliters:

2 x 1000 = 2000 milliliters, so she is using a 2,000 milliliters pincher.

Now we have to multiply the number of friends (10) by the amount of lemonade she serves to each one (400 ml)

400 x 10 = 4,000 milliliters

Finally, we have to divide the amount of lemonade she needs to serve (4,000 ml) by the capacity of the pitcher (2,000), to obtain the number of times that she will need to fill the pitcher.

4,000/2,000=2 times

Feel free to ask for more if needed or if you did not understand something.
