Answers:
The area for the square on the left is 81m^2. This is found because all sides of this square are the same, so the length and width are the same. Just multiply 9 x 9.
The area for the triangle is 31.5m^2. We find the left side is 9 meters because the triangle shares the same side as the square on the left side. We also find the bottom side is 7 because that is the length of each side of that square because all sides on a square is the same. We then multiply 9 times 7, getting 63, we divide this by 2 because it’s a triangle.
The square on the right has the area of 225 because both length and width is 15.

Answer: x = -6</h2>
<h3>
Step-by-step explanation:</h3>
To solve for x, we have to find a way to make x the subject of the equation (get x on one side and everything else on the other side)
<h3>
</h3>
since -4 = (2/3)x [mutiply both sides by 3]
⇒ -4 × 3 = 2x [divide both sides by 2]
⇒ (-12/2) = x [simplify by dividing -12 by 2]
∴ x = -6
60 percent of 1200 is 720 if that’s what you mean
Question 2 would be 6+3+n=12
Answer:
4
Step-by-step explanation:
- Add up your data. 3+13+11+5=32
- Divide the sum by the number of data you have. In your case you would divide 32/4/
- This will give you 8, which is your mean. Now, subtract 8 from each value and put the difference to its absolute value.
- Now, add up each of these values (5+5+3+3=16), then divide by 4. This will give you an answer of 4.
Hope this helps! Have a great day :)
