Answer:
12
Step-by-step explanation:
Ok, first write it as an equation, 3x-12=24. Next, you need to simplify, add 12 to each side, getting 3x=36. Lastly, subtract 3 from each side which gives you x=12
Difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
25=5^2
x^2-5^2=(x-5)(x+5)=0
set to zero
x-5=0
x=5
x+5=0
x=-5
x=5 or -5
A
