In the picture with the triangles Phillip is correct because the triangle does not give the measurements of the same side so there is no proof of any sides to be the same. With the other picture what I did was I reversed the translation which got the points A (-2,1) B (-5,3) Then I reversed the rotation which got me A(2,-1) and B (5,-3). So line AB endpoints would be located A (2,-1) and B (5,-3).
Hope this helps!
You can graph this two ways. You can change it into slope intercept form, y=mx+b, or find the x- and y-intercepts. To change it to slope intercept form you would need to add 12x to both sides and divide both sides by 18. By doing this, you'd get y=2/3x+17/9. You'd then go up on the y-axis to 17/9 or 1.89 and place a point. You'd then go up two and to the right three and place another point. You can do this one more time and connect the points. To find the x- and y- intercepts you would plug 0 in for x and solve for y, getting 17/9, and plug 0 in for y and solve for x, getting -17/6. You'd then plot the points (-17/6, 0) and (17/9) and connect the points forming a line.
I think the answer is 240 :)
Answer:
<h2><u>
72 square units</u></h2>
Step-by-step explanation:
First let's find the area of the middle rectangle.
We know the width of this rectangle is 6 and the length is 8 so we will multiply these two numbers.
6 × 8 = 48
Now let's find the area of the triangles
The formula is ((length × width) ÷ 2)
The width is 3, as it is not part of the rectangle, and the length is 8
And there are two triangles so we will do this twice
((8 × 3) ÷ 2) = 12
((8 × 3) ÷ 2) = 12
Now add up all of the areas
48 + 12 + 12 = 72
<u>So 72 is our final answer</u>
