Question

Crying help me please :(

Answer 1

(5x)/5=4/x
x=4x
x^2=4
x=2

Answer 2

AB = 10

EF = 2

Explanation:

to find the scale factor you have to divide the bigger scale by the smaller one which would be

(5x)/5 and 4/x

since both scale factors should be the same you can set them even to each other

(5x)/5=4/x

solve for x

(5x)/5=4/x

x=4/x

x^2=4

x=2
