Answer:
441 
Step-by-step explanation:
If this is a rectangle, meaning the width and the legnth is different, there is no way in solving this.
However, if it is a square, meaning all the sides are the same,
we can know that every side is 21 inches long.
An area is the width times the length, which is both 21 in this case.
21 times 21 = 441.
441 inches squared.

Answer:
290 days
Step-by-step explanation:
We know the starting cost is $500. Suppose the commercial is aired x times. That means the cost will be a total of 50x.
Adding that to 500, we get a total of 50x + 500.
The company's budget is only $15,000, so we set this equal to 50x + 500 to find x:
50x + 500 = 15,000
50x = 14,500
x = 290
The answer is 290 days.
<em><u>Correct steps are shown</u></em>
<em><u>Correct simplified expression is:</u></em>
<em><u>Solution:</u></em>
<em><u>Given that: Mara simplifies the expression</u></em>
<em><u>Correct steps are:</u></em>
From given,
<em><u>Use the distributive property,</u></em>
a(b + c) = ab + bc
Therefore,
Group the like terms
Thus the expression is simplified
Y(toy’s new price)=x(original toy price)- .15x(15% of toy price)
the equation for this would be y=x-.15x, i don’t know if this really helps, i can help if you need more help.
