Find the area of this figure.
AlladinOne [14]

Answer:

216 cm^2

Step-by-step explanation:

Alright, first lets knock out the rectangle. This would be found by doing L * H. For the length it would be 14. For the height, it would be 12.

14 * 12 = 168

Next with the triangle, it has a length, or "base" of 8 and the same height of 12. For a triangle, do (B * H) / 2 as the formula.

(8 * 12) / 2

96 / 2

48

Now, combine these two values to get the total:

168 + 48 = 216 cm^2

All done!

Find the missing value so<br> that the two points have a<br> slope of 2/7.<br> (-1,-1) and (x,1)
Radda [10]

Answer:

x = 6

Step-by-step explanation:

Slope = (y(2) - y(1))/(x(2) - x(1))

(-1 - 1) / (-1 - x)

If the slope is 2/7, it would be (-2/-1-x, where x would have to be 6)

(-2)/(-7) = 2/7, so x = 6

Check:

(-1 - 1) / (-1 - 6)

(-2)/(-7)

2/7 (Correct :))

Hope it helps :D
