\huge\text{Hey there!}

\textsf{(9 - r)(2 - 3r)}

\textsf{= 9(2) + 9(-3r) + 2(-r) + (-r)(-3r)}

\mathsf{= 18 - 27r - 2r + 3r^2}

\mathsf{= 3r^2 + 18 - 27r - 2r}

\boxed{\large\text{COMBINE the LIKE TERMS}}

\mathsf{= 3r^2 + 18 + (-27r - 2r)}

\mathsf{= 3r^2 + 18 - 29r}

\mathsf{= 3r^2 - 29r + 18}

\boxed{\large\textsf{Therefore, your answer is: \large\boxed{\mathsf{3r^2 - 29r + 18}}}}\large\checkmark

\huge\text{Good luck on your assignment \& enjoy your day!}

What is the vertex of this parabola? y= 2x² + 4x +5
uranmaximum [27]

Answer:

vertex = (- 1, 3 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

y = 2x² + 4x + 5 ← is in standard form

with a = 2, b = 4, then

x_{vertex} = - \frac{4}{4} = - 1

Substitute x = - 1 into the equation for corresponding value of y, that is

y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3

vertex = (- 1, 3 )
