Answer:

  x = -6 or 6

Step-by-step explanation:

The square root is always positive, so the equation simplifies to ...

  \sqrt{4x^2}-\sqrt{x^2}=6\\\\2|x|-|x|=6\\\\|x|=6\\\\x=\{-6,\ 6\}

_____

The graph shows the solutions to f(x) = 0, where f(x) = √(4x²) -√(x²) -6.

The area of a square garden is 98m squared. How long is the diagonal?
aleksley [76]

Answer:

diagonal is 14 m

Step-by-step explanation:

We are given;

  • The area of a square garden as 98 m²

We are required to determine the diagonal of the square.

We know that;

Area of a square = s²  , where s is the side of the square

Therefore;

s² = 98

Thus;

s = √98

To get the diagonal

s² + s² = diagonal squared

Hence;

Diagonal squared = (√98)² + (√98)²

                              = 98 + 98

                              = 196

Thus;

Diagonal = √196

               = 14 m

Thus, the diagonal is 14 m
