Answer:

It's Halloweeeeen

Step-by-step explanation:

(I took Geometry before and I still have my notes). To find the area of the rectangle, you'd multiply 12 x 9 because the rEcIpE for it is length x width (A=lw). Whe you do that, you get 108.

To find the area of the triangle, you have to multiply the base and the height, then divide that by 2. The recipe for that is 1/2 base x height (A=1/2bh). The base of the triangle is equal to the height of the rectangle (which is 9). So you'd be multiplying 9x7 which equals 63, then dividing that by 2 which is 31.5.

After all that, you add 108 and 31.5 to get 139.5cm squared! Hope this helped :3

Answer: C. (2, -5 )

Step-by-step explanation:

These are the coordinates of the points on the line

We can see (-3, 5) and (0, -1) on the line.

To find the y-coordinate of a point when the x-coordinate is 2, all you have to do is look for the x-intercept of 2 and look for the y-intercept.

When you look at the bottom of the graph, you can see that the x-coordinate 2 and the y-coordinate -5 intersect to form a point.

Hope that helped!
