Answer:
Its 9.0 units
Step-by-step explanation:
For the side mostly to the left, its gonna be 3 units, since we can easlily count it
Now, for the diagonals, we have to use the formula for the area of a triangle, which is (l * w) / 2 = a.
For the bottom side, its 3 along the x axis and 1 along the y axis. 3 * 1 is 3, now divide that by 2 and you got 1.5
Now, for the right side, its 5 on the y, 1 on the x. Multiply 1 by 5, you got 5. Now divide that by 2 and you have 2.5
Finally, for the top side, its 4 on the x, and 1 on the y. 4 * 1 is 4, divided by 2 and its 2.
Alright, now we have to add 'em all together. 3 + 1.5 + 2.5 + 2 is 9 units
Theres your answer :)
Answer:
If there are any rational roots, it would be a factor of your constant term (9) divided by a factor of the high-order coefficient (12).
The answer to 20 divided by 70 is
0.2857
For rounding, you look at the number to the right of it.
In this case, it would be 7
because 7 is greater than 5, it is rounded up (remember, 5 and up is round up, while 4 and lower is round down)
So her answer should be 1300
hope this helps
