Answer:
12
Step-by-step explanation:
We can see that the base TA is 4, and the second base RS is 2. We can see that the height is 4. The area of a trapezoid is:

Using this, we can substitute, and get:

Answer: m = -2
Step-by-step explanation: To get from one point to the next along this line,
we must first go down 2 units so we say that our rise is -2.
From there we move 1 unit to the left so our run is 1.
So our slope or rise over run is -2/1 or -2.
Answer:
The slope is -9/2 and the y intercept is 28
Step-by-step explanation:
We want to put this in slope intercept form
y = mx+b where m is the slope and b is the y intercept
18x + 4y = 112
Subtract 18x from each side
18x+4y-18x = -18x+112
4y = -18x+112
Divide each side by 4
4y/4 = -18x/4 +112/4
y = -9/2x + 28
The slope is -9/2 and the y intercept is 28
