It keeps saying my answer is wrong
mariarad [96]
Since the formula is \frac{1}{2}h(B1+B2), here's the answer.

First we do \frac{1}{2}10, which gives us 5.

Then we do 5(20+8), which gives us 5(28).

At last we do 5*28, and we get 140.

So, the answer would be 140.

Hope this helped! c:

Which pair of points have equal X coordinates?
Varvara68 [4.7K]
Points Q and R. Their coordinates are R=(-5,-7), Q=(-5,6). The first number is the X-intercept. Both Q and R have -5 have -5 as their first number. You can tell this by drawing two line from the x-axis (horizontal) and the y-axis (vertical) and see where they meet up. See what numbers the coordinates are, and presto, you have your answer!
Hope that help!
