Answer:
Step-by-step explanation:
1/3 x 1/3 in exponential notation is 1/3². you are multiplying a number by itself so its squared, ig you are multiplying a number by itself three times, then its cubed, with a 3.
4(x - 7) + 12 = 20
4(x) - 4(7) + 12 = 20
4x - 28 + 12 = 20
4x - 16 = 20
+ 16 + 16
4x = 36
4 4
x = 9
