we know that

the area of the complete square is equal to

As=b^{2}

where

b is the length side of the square

b=8m

so

As=8^{2}

As=64m²


the area of one corner is equal to the area of a triangle


\frac{x^{2}}{2}

so

the area of 4 corners is equal to

\frac{x^{2}}{2}*4=2x^{2}


the area A of the resulting figure as a function of x is equal to

area of the square minus the area of 4 corners

A=(64-2x^{2})m²


the answer is

A=(64-2x^{2})m²

The area ( A ) of the resulting figure:
A = s² - 4 · x²/2 
A = 8² - x² / 2
A = 64 - x²/2
Answer:
The area is 64 - x² / 2.

Which equation is true when r = 7 ?
jeka57 [31]

Answer:

7 = 49 ÷ r

Step-by-step explanation:

To find the equation that is true when r = 7, we need to find a number after the equals sign that is a multiple of 7.

Multiples of 7:  

7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77...

Therefore, the only answer option in which the number after the equals sign is a multiple of 7 is:

7 = 49 ÷ r

To prove this, input r = 7 into each of the equations:

   6 = 30 ÷ r

⇒ 6 = 30 ÷ 7

⇒ 6 ≠ 4.285... ← incorrect!

   7 = 54 ÷ r

⇒ 7 = 54 ÷ 7

⇒ 7 ≠ 7.714... ← incorrect!

   7 = 49 ÷ r

⇒ 7 = 49 ÷ 7

⇒ 7 = 7 ← correct!

   9 = 72 ÷ r

⇒ 9 = 72 ÷ 7

⇒ 9 ≠ 10.285... ← incorrect!
