To simplify the square roots, we apply the square root to the number first, followed by the variable. So for 9x^2, we take the square root of 9 (which is 3), then the square root of x^2 (which is x).
The square root of (9x^2) is 3x. The square root of (18y^2) is (3sqrt2)y. Dividing the first term by the second term gives:x / y(sqrt2).If the final answer must be rationalized, it should be x(sqrt2) / 2y.
Here a right angled triangle given. We know that one angle of a right angled triangle is 90°.
As the sum of three angles of a triangle is 180°, so we can say the sum of other two angles of a right angled triangle is (180-90)° = 90°.
Here in the figure the other two angles given and . Sum of these two angles is 90°.
So we can write the equation as,
We have to remove the parenthesis now.
Now we will add the like terms. Here x and 2x are like terms. By adding them we will get,
To solve it for x, now we have to move 15 to the other side by subtracting it from both sides.
Now to get x, we have to move 3 to the other side, by dividing it to both sides.
We have got the required value of x.
The solution is x= 25.

We know $65 were spent on his ticket and some shirts.Which he used 32.25 which leaves us with 27.75 and a shirt cost 14 and 50 cent .
SO you need to divide 27.75 in 14 and 50 cents which is equal to
14 plus 14 equals 28
75 plus 50 equals 1 and 25 cents
David can buy two shirts
