Answer: scale factor = 1.5

Step-by-step explanation:

\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Side length of original figure}}

Given: Triangle ABC is a scaled copy of triangle DEF.

Side AB = 12 cm and is the longest side of ABC.

Side DE = 8 cm and is the longest side of DEF.

\text{For similar triangles, Corresponding sides are proportional.}

AB is corresponds DE (longest side of both triangles)

So, \text{Scale factor}=\dfrac{\text{AB}}{\text{DE}}=\dfrac{12}{8}=1.5

Hence, the scale factor = 1.5.

Is the product of 2 perfect squares always a perfect square?
nexus9112 [7]
<span> The product of two perfect squares is a perfect square.

Proof of Existence:
Suppose a = 2^2 , b = 3^2 [ We have to show that the product of a and b is a perfect square.] then
c^2 = (a^2) (b^2)
= (2^2) (3^2)
= (4)9
= 36
and 36 is a perfect square of 6. This is to be shown and this completes the proof</span>
