Answer:
C) 20
Step-by-step explanation:
ab=15
5*3 = 15
which is a and which is b
a - b = +2
5 - 3 = + 2
------------------
a = 5 and
b = 3
------------------
a3-b3 = 53 - 33 = 20
Squared in this case just means to multiply the fraction by itself.
3/2 * 3/2 = 9/4 which equals 2 1/4. Or in decimal form, 2.25.
Hope I helped and good luck!
