Find the length of side x in simplest radical form with a rational denominator

the image of (6, 9) under a dilation is (4, 6). the scale factor is

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

pi x^2

step-by-step explanation:

pi times x squared
