This problem can be solved by calculating the area of the figure before removing the triangles, then subtracting the combined area of the triangles.

First, we have to find the area of the original composite figure.  It appears that the figure consists of a 16 ft by 16 ft square with an 8 ft by 8 ft square cut out:

SA = (16*16) - (8*8)

SA = 256 - 64

SA = 192

The ORIGINAL area of this composite figure is 192 ft².  Now we have to find the area of the removed triangles.  Triangle area is found using half base times height.  The base and height of each triangle appears to be 8, so we can plug in :

TA = \frac{1}{2}(b * h)

TA = \frac{1}{2}(8 * 8)

TA = \frac{1}{2}(64)

TA = 32

The area of each triangle is 32 ft².  Finally, we should subtract the 3 triangles' area from the composite figure's area:

SA - 3(TA)

192 - 3(32)

192 - 96

96

The shaded region's area is 96 ft².

A line with slope
spayn [35]

Answer:

(0, 8/3) = y-intercept

Step-by-step explanation:

I chose to find the y-intercept since it is easy to find with the given information.

The equation for a line is y = mx + b

To find the y-intercept, we must plug in the info we have and solve for b:

4 = -1/3 (-4) + b

4 = -4/3 + b

8/3 = b

To find a point on the line, you also could have added -1 to 4 and 3 to -4 since slope means rise/run or change in y/change in x:

(y - 1) / (x + 3) = (4 - 1) / (-4 + 3) = (3, -1) (flip since it's the y and x coordinate) = (-1, 3)

I need answers for them three
sergeinik [125]
These are the answers. You subtract 6 from -3 giving you n≥-9. Since n/3 is a fraction, in order to undo it we must multiply it to the other side, giving us n≤-63.

1. n≥-9
3. n≤-63

I hope it helped!
