Hi i really need help with my geometry please

Step-by-step explanation:

since the base angles of a triangle are equal the given triangle an isosceles triangles.

therefore side x is also 9 because the two sides of an isosceles triangle is equal.

Now for side y

using pythagoras theorem

a^2 + b^2 = c^2

9^2 + 9^2 =y^2

81 + 81 = y^2

162 = y^2

= y

=y

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
