Which scale factor would produce a contraction? a.) 5/2 b.) 1.2 c.) 2.3 d.) 3/4

We know that
the scale factor produce a contraction when its value must be less than zero

Let
SF> scale factor
SF< 0> produce a contraction
A.) 5/2 > 2.5   SF>0  not produce a contraction
B.) 1.2 > 1.2   SF>0  not produce a contraction
C.) 2.3 > 2.3   SF>0  not produce a contraction
D.) 3/4> 0.75   SF< 0   produce a contraction

the answer is 3/4

48x^7y^3. the app is photomath

The answer is c. 7 (i think) i’m almost sure though
