If a quadrilateral has sides that measure 4 in. and angles that all measure 90°, we can consider the quadrilateral to be a/an a. square. b. natural polygon. c. decagon. d. irregular polygon.

the answer is square.

quadrilateral is four sides so if all sides are 4 inches in length and at a 90 degree angle it makes it a square.

 The correct option is (A) Square.

Step-by-step explanation:  Given that a quadrilateral has sides that measure 4 in. and all the angles measure 90°.

We are to select the type of the quadrilateral.

Since a quadrilateral has 4 sides, so it cannot be a decagon. Because a decagon has 10 sides.

The sides of the quadrilateral are equal, so it cannot be an irregular polygon. Because an irregular polygon do not have equal sides.

We know that a quadrilateral with all sides equal and all angles with measure 90° is a SQUARE.

So, the given quadrilateral is a square, because all its sides are equal (4 in.) and all the angles measure 90°.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
