Answer:

Quadrilateral ABCD is a rectangle (more specifically a square)

Quadrilateral WXYZ is not a rectangle

Step-by-step explanation:

A rectangle is a quadrilateral with four straight sides, two sets of parallel sides, and four right angles. Quadrilateral ABCD is a rectangle because it fits all of the criteria. Quadrilateral WXYZ is not a rectangle because it does not have four straight sides or four right angles.

(x+4)²-x²=0 hãy tìm x

harina [27]

Answer:

<h2><em><u>I hope this helps to :)</u></em></h2><h2><em><u>If so can you mark me as Brainliest please ?</u></em></h2>

Step-by-step explanation:

Let's solve your equation step-by-step.

$(x+4)^{2} -x^{2} =0$

Step 1: Simplify both sides of the equation.

$(x+4)^{2} -x^{2} =0$

$x^{2} +8x+16+-x^{2} =0$ (Distribute Law)

$(x^{2} + -x^{2})+(8x)+(16)=0$ (Combine Like Terms)

$8x+16=0$

$8x+16=0\\\\$

Step 2: Subtract 16 from both sides.

$8x+16-16=0-16\\8x=-16$

Step 3: Divide both sides by 8.

$\frac{8x}{8} =\frac{-16}{8}$

x=−2
