Answer:
○ B. No, <em>x</em><em> </em>= -2 is not a zero of the polynomial.
the quotient is x - 2, and the remainder is -221.
Step-by-step explanation:
[x - 15][x + 15] >> Factored Form
Obviously, this is not a zero. Now, to get the remainder, we have to plug in the vertical line of x = -2 into its conjugate, meaning an expression with opposite signs, which is x + 2. This is the expression we divide the dividend by, so you will have this:
Since the divisor is in the form of <em>x</em><em> </em><em>-</em><em> </em><em>c</em><em>,</em><em> </em>using<em> </em>Synthetic Division, we get this:
You see? You have <em>x</em><em> </em><em>-</em><em> </em><em>2</em><em> </em>in the quotient, and you have -221 as the numerator remainder.

No not all squares are congruent to each other they all have longer sides than others
Answer:
9 square units
Step-by-step explanation:
Draw a rectangle around the triangle. The rectangle is 4 units tall by 6 units wide. The area of the triangle equals the area of the rectangle minus the triangles in the corners.
A = (4)(6) − ½(2)(4) − ½(1)(4) − ½(3)(6)
A = 24 − 4 − 2 − 9
A = 9
