The equation is 
-
= 
Solution
<u>Step 1:</u>
Take square on both sides, we get
3x - 2
-2 = x +2
<u>Step 2:</u>
Subtract 3x - 2 from both sides, we get
-2
<u>Step 3:</u>
Again, square on both sides in order to get rid of the square root from the above equation, we get
Now we have to simplify it,
<u>Step 4:</u>
Now we have to solve this quadratic equation, in order to get the solution.
We get x = 2 and x = -2, When we verifying solution in the original given equation, the solution does not satisfy the equation.
Reason: We get negative number in the square root.
Therefore, it has no Roots.
<em>Answer: b) No roots</em>
First, I would find the radius for both discs. To do so, divide the circumference by 2.
So.. 27.3/2=13.65. 22.5/2=11.25.
Afterwards, take the radius and use the formula: 2(3.14)r.
2*3.14*13.65＝85.722 and 2*3.14*11.25＝70.65.
Then, you subtract 85.722 from 70.65 which equals 15.072 which rounds to 15.
Add up all the amounts of marbles, which gives you 52, then see how many greens ones there are.
So the answer would be 10/52
If you do 3 houses in one day then that would be 8 hours and 25 minutes.
2 hours and 45 min * 3
Hello!
To find the surface area of the given cylinder, we need to use the formula of the surface area of a cylinder.
The formula for the surface area of a cylinder is SA = 2πrh + 2πr².
In this formula, r is the radius and h is the height.
In the given diagram, we see that the height is 6 meters, and the radius 9 meters. With those values, we can substitute them into our formula and solve for the surface area.
In some cases, you are given the diameter. To find the radius, you would need to divide the diameter by two.
SA = 2π(9)(6) + 2π(9)²
SA = 54(2π) + 2(81π)
SA = 108π + 162π
SA = 270π
SA ≈ 848.2 m²
Therefore, the surface area of the given cylinder is choice A, 848.2 m².
