Answer:

2a-b

Step-by-step explanation:

We can start by grouping our A's and B's, while making sure to keep their individual signs.

For our A's, we get 3a-a and for our B's, we get 2b-3b.

When we simplify our A's, we get 2a and when we simplify our B's, we get -b.

After grouping them back together, you end up with 2a-b.

What is the area? Round to the nearest tenth
Tamiku [17]

Answer:

60.8 mm^2

D

Step-by-step explanation:

Remark

You have to assume that the left and right sides are both 9.3. The question is undoable without that assumption.

Next, you have to assume that The top is 7.8 mm across and both ends meet 9.3 at right angles. Again if that is not true, the problem can't be done. Sometimes people making these questions make errors which you are asked to correct.

Solution

So let's assume that everything I've assumed is correct.

Find the area of the rectangle.

Area = L*W

L = 9.3

W = 7.8

Area = 7.8 * 9.3

Area = 72.54        Do your rounding at the end.

Now find the are of the triangle that has been cut out.

The height = 3

The base = 7.8

Area = 1/2 b * h

Area = 1/2 7.8 * 3

Area = 11.7

The area of the figure = area of the rectangle - the triangle's area

Figure Area = 72.54 - 11.7

Figure Area = 60.84
