Answer:
x = 14
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define equation</u>
4(x + 4) = 6(x - 2)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 4x + 16 = 6x - 12
- Subtract 4x on both sides: 16 = 2x - 12
- Add 12 on both sides: 28 = 2x
- Divide 2 on both sides: 14 = x
- Rewrite: x = 14
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 4(14 + 4) = 6(14 - 2)
- Add/Subtract: 4(18) = 6(12)
- Multiply: 72 = 72
And we have our final answer!
Answer:
69 meters squared
Step-by-step explanation:
You can split the shape into two small rectangles by drawing a vertical line. Then, you can solve for the areas of the two rectangles separately and then add them together.
The larger rectangle would have an area of 5 * 12, or 60 m^2.
The smaller rectangle would have an area of 3 * 3, or 9 m^2.
Simply add those together and the total area would be 69 m^2.
First find the difference.
160-40=120.
Now find the increase percentage:
120/40=3
It increased 300%.
