Answer:

In this case, you first have to make the right side of the equal sign one number, so you'd have to do 30 - 30 which equals 0. Now you divide 30 from both sides of the equal sign, in order to get x by its self. Since you can't divide 0 by 30, your answer will just be 0/30.

So x = 0/30 or 0 .

I really hope this makes sense, and if you like this answer can you please mark me brainliest, I only need one more to reach my goal? :)

Answer: 52.5cm²

Step-by-step explanation:

Firs, you have to split this composite shape into two separate shapes; a rectangle and triangle.

To work out the area of the rectangle you would have to do 8x5=40.

To work out the area you would have to find out the height of it first. So, to do this you would have to do 1+2=3 then do 8-3=5. Now we know the height is 5.

Then you have to use the formula base times height divided by 2 (b×h/2). So 5×5=25 then 25÷2=12.5

To then find the total area of this composite shape you would have to add the two areas together. So 40+12.5=52.5cm²

Hope this helps :)
