1 answer:

5 0

$2x^2+y^2 = x^2-y^2\\\\
2x^2 - x^2 + y^2 + y^2 = 0\\\\
x^2 + 2y^2=0\\\\
x^2 = 0~~~\Longrightarrow~~~\boxed{x=0}\\\\
2y^2 = 0~~~\Longrightarrow~~~y^2 = 0~~~\Longrightarrow~~~\boxed{y=0}\\\\

The length of a rectangle is represented by (6x − 2), and the width is represented by (x − 1). Which expression best represents

Olenka [21]

The are of a rectangle can be obtained by using the formula

A=L*W

Since we are already given with the L, which is (6x-2), and the width, which is (x-1), the area of the rectangle is then

A = (6x-2)(x-1)

which, upon further simplification will give us

A = 6x^2-2x-6x+2

Combining like terms will yield

A = 6x^2-8x+2

Hence, the area of the specified rectangle is represented by the expression 6x^2 -8x +2.
