Answer:
x = 6
Step-by-step explanation:
2/(x-2) = 5/(4+x) - set up the ratios of similar sides
2(4 + x) = 5(x - 2) - cross multiply to solve
8 + 2x = 5x - 10 - simplify
18 = 3x - simplify to get x on one side of the equation
6 = x - divide both sides of the equation by 3 to isolate x
Answer: 4 tiles
Explanation: if the square has a width of one foot then the length is also one foot since all sides are equal. Therefore 4 squares can fit along a 4 foot wall

3m³ - 4m² + 8 - (-4m³ + 7m² - 5m - 9)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute negative: 3m³ - 4m² + 8 + 4m³ - 7m² + 5m + 9
- Combine like terms (m³): 7m³ - 4m² + 8 - 7m² + 5m + 9
- Combine like terms (m²): 7m³ - 11m² + 8 + 5m + 9
- Combine like terms (Z): 7m³ - 11m² + 5m + 17
Square root 9e^2f and 49
then divide by 9
Answer:
3/7
Step-by-step explanation:
Use Y2-Y1/X2-X1
So, 7+2/7+14=9/21
9/21 can be simplified so divide both by 3 which leaves you with 3/7
