Answer:
<em>9/5</em>
Step-by-step explanation:
- Create an Equation: <em>x^2 = 3 + 6/25</em>
- Simplify the Right Side: <em>3 + 6/25 = 75/25 + 6/25 = 81/25</em>
- Substitute the Values back into the Equation: <em>x^2 = 81/25</em>
- Solve for x by taking the Square Root of Both Sides: <em>x = √81/25</em>
- Simplify: <em>x = √81/√25 = 9/5</em>

Answer:
Step-by-step explanation:
Consider -7-4r=-15. Adding 7 on both sides of the equation,
-4r=-8 --- r = 2
Plug in value of r in r/2 + 9 = 2/2+9 = 1+9 = 10
Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 9² = 16²
x² + 81 = 256 ( subtract 81 from both sides )
x² = 175 ( take the square root of both sides )
x = 
= 5 ≈ 13.23 units ( to 2 dec. places )
