Let c = 10.Which expression makes the comparison true.
den301095 [7]

Answer:

c² - 63

Step-by-step explanation:

4c - 10 = 30

3c ÷ 3 = 10

c² - 63 = 37

c² ÷ 10 = 10

Since c² - 63 = 37 and c + 25 = 35, 37 is greater than 35 so it would make sense to choose c² - 63 as the answer.

c + 25 < 37

I hope this helps you :D

The length of a diagonal of a square is 18√2 inches. Find the perimeter of the square.
Leona [35]

A diagonal of a square is defined, d=a\sqrt{2} where <em>a</em> is side of the square. Solve for <em>a</em> to get a=\frac{d}{\sqrt{2}}.

Now multiply <em>a</em> by 4 since that is the definition of a perimeter,

P=4a=4\cdot\frac{18\sqrt{2}}{\sqrt{2}}=4\cdot18=\boxed{72}.

Hope this helps.
