Let's work through some of the problems in this image.

### Problem 15
We are asked to find the distance between two points \( K(0, 5) \) and \( L(7, 9) \). The distance formula is:

\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]

Substitute the values:

\[
d = \sqrt{(7 - 0)^2 + (9 - 5)^2} = \sqrt{7^2 + 4^2} = \sqrt{49 + 16} = \sqrt{65}
\]

The square root of 65 is approximately 8.1, so the distance is **8.1 units**.

### Problem 16
For points \( C(-2, 6) \) and \( D(10, -8) \), using the same formula:

\[
d = \sqrt{(10 - (-2))^2 + (-8 - 6)^2} = \sqrt{(10 + 2)^2 + (-8 - 6)^2} = \sqrt{12^2 + (-14)^2} = \sqrt{144 + 196} = \sqrt{340}
\]

The square root of 340 is approximately 18.4, so the distance is **18.4 units**.

### Problem 17
For points \( W(-3, -5) \) and \( X(-9, 4) \):

\[
d = \sqrt{(-9 - (-3))^2 + (4 - (-5))^2} = \sqrt{(-9 + 3)^2 + (4 + 5)^2} = \sqrt{(-6)^2 + 9^2} = \sqrt{36 + 81} = \sqrt{117}
\]

The square root of 117 is approximately 10.8, so the distance is **10.8 units**.

### Problem 18
For points \( G(-12, -11) \) and \( H(5, -9) \):

\[
d = \sqrt{(5 - (-12))^2 + (-9 - (-11))^2} = \sqrt{(5 + 12)^2 + (-9 + 11)^2} = \sqrt{17^2 + 2^2} = \sqrt{289 + 4} = \sqrt{293}
\]

The square root of 293 is approximately 17.1, so the distance is **17.1 units**.

### Problem 19
For points \( A(6, 2) \) and \( B(-3, -1) \):

\[
d = \sqrt{(-3 - 6)^2 + (-1 - 2)^2} = \sqrt{(-9)^2 + (-3)^2} = \sqrt{81 + 9} = \sqrt{90}
\]

The square root of 90 is approximately 9.5, so the distance is **9.5 units**.
