The greatest common factor for 24 and 60 is 12. To solve just make it a fraction.
24/60 then divide until there's nothing in common anymore. Then you add the numbers you divide. So if you divided by three four times or vise versa then you'd get 12.
Hope that helped. C=
Step-by-step explanation:
Rewrite the expression using only positive exponents. Then, evaluate the expression. 3^{-2}
Answer:
D
Step-by-step explanation:
Factor the numerators/ denominators
10 - 5 = 5(2a - 1) ← common factor of 5
4a² - 1 = (2a - 1)(2a + 1) ← difference of squares
[ Change ÷ to × and turn second fraction upside down ]
=
× 
[ cancel the factor (2a - 1) on the numerator/denominator ] leaving
=
=
