Find the area of the hexagon

2 answers:

Answer:

The area is 78 square inches

Step-by-step explanation:

so you can split the hexagon into two trapezoids, and then find the area of one of those trapezoids, which is what I did. The area of a trapezoid I think is

a, b=base, h=height

A=a+b/2*h

is a really bad way of saying it, but that's how I know to do it.

So anyways I just substituted the numbers with their corresponding letters and solved. So the area of one trapezoid was 39, and since we have two 39's, you do 39*2 and you get 78.

Hope I helped

Answer:

$y^2 + 8y + 16$

Step-by-step explanation:

$(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =$

The first set of parentheses is unnecessary, so it can just be removed.

$= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)$

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

$= 6y^2 + 2y + 5 - 5y^2 + 6y + 11$

Now you combine like terms.

$= 6y^2 - 5y^2 + 2y + 6y + 5 + 11$

$= y^2 + 8y + 16$

<h3>Solution (Line 2): <u>(Refer to graph 1)</u></h3>

<u>Note that:</u>

Given points: (0, -2) and (1, -4)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

<u>Use the slope formula to find the slope.</u>

Rise/Run = Slope
=> Rise = -2; Run = 1
=> Rise/Run = -2/1 = -2

<u>Use the point slope form formula.</u>

y - y₁ = m(x - x₁) = Equation of line.
=> y - (-4) = -2(x - 1) = Equation of line.
=> y + 4 = -2x + 2
=> y = -2x + 2 - 4
=> y = -2x - 2

<h3>Solution (Line 3): <u>(Refer to graph 2)</u></h3>

<u>Note that:</u>

Given points: (0, -2) and (-4, 3)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

<u>Use the slope formula to find the slope.</u>

Rise/Run = Slope
=> Rise = -5; Run = 4
=> Rise/Run = -5/4

<u>Use the point slope form formula.</u>

y - y₁ = m(x - x₁) = Equation of line.
=> y - 3 = -5/4{x - (-4)} = Equation of line.
=> y - 3 = -5/4{x + 4}
=> y - 3 = -5x/4 - 5
=> y = -5x/4 - 2

<h3>Solution (Line 4): <u>(Refer to graph 3)</u></h3>

<u>Note that:</u>

Given points: (0, -2) and (-3, -5)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

<u>Use the slope formula to find the slope.</u>

Rise/Run = Slope
=> Rise = 3; Run = 3
=> Rise/Run = 3/3 = 1

<u>Use the point slope form formula.</u>

y - y₁ = m(x - x₁) = Equation of line.
=> y - (-5) = 1{x - (-3)} = Equation of line.
=> y - (-5) = 1{x + 3}
=> y + 5 = x + 3
=> y = x - 2
