The diagonal of a square is obtained by using Pythagorean theorem. Letting x be the side of the square,
x² + x² = 14²
Solving x from the equation gives x a value of approximately 9.899 m. The perimeter of a square is four times the length of its side. Thus, the perimeter of the square is approximately 39.60 meters.
Answer:
9+(-8)
Step-by-step explanation:
8-(-9) is subtraction
9+8 would not give you a difference
8+(-9) would give you a negative number
so 9+(-8) is the right answer
If you want to make 10, you can take 3 from the 13 and add it to the 7. You will then have 10+10 which equals 20.
We can do anything to an equation as long as we do it to both sides
given:

square both sides

minus 3 from both sides

multiply both sides by 6
![(4+\sqrt{x+3})^2=36 square root both sides, remember to take the positive and negative roots [tex]4+\sqrt{x+3}=+/-6](https://tex.z-dn.net/?f=%284%2B%5Csqrt%7Bx%2B3%7D%29%5E2%3D36%20square%20root%20both%20sides%2C%20remember%20to%20take%20the%20positive%20and%20negative%20roots%20%5Btex%5D4%2B%5Csqrt%7Bx%2B3%7D%3D%2B%2F-6)
minus 4

square both sides
do for -4+6 and -4-6 (2 and -10)

and

minus 3

x=97 doesn't work
the answer is x=1
Answer: y= -41
Step-by-step explanation:
Move all terms not containing y to the right side of the equation.
