Problem

Paraphin [41]

Answer:

45/126 or 5/14

Step-by-step explanation:

a / b = 5/8

b / c = 9/14

a = 5

b = 8

b = 9

8 * 9 = 72

b = 72

If b was = 8 and now = 72, multiply a by 9.

b = 45

If b was 9 and now is 72, multiply c by 9.

c = 14 * 9 = 140 - 14 = 126

b / c = 45/126 or 5/14

You are welcome!

Answer:

$\sqrt{37}$

Step-by-step explanation:

To find the distance between a point (m, n ) and the line

Ax + By + C = 0

d = $\frac{|Am +Bn+C|}{\sqrt{A^2+B^2} }$

Here (m, n) = (6, 2) and rearranging the line

6x - y + 3 = 0 ← in general form

with A = 6, B = - 1 and C = 3 , then

d = $\frac{|6(6)-1(2)+3|}{\sqrt{6^2+(-1)^2} }$

= $\frac{|36-2+3|}{\sqrt{36+1} }$

= $\frac{37}{\sqrt{37} }$

Rationalise the denominator by multiplying numerator/ denominator by $\sqrt{37}$

= $\frac{37}{\sqrt{37} }$ × $\frac{\sqrt{37} }{\sqrt{37} }$

= $\frac{37\sqrt{37} }{37}$ ← cancel 37 on numerator/ denominator

= $\sqrt{37}$
