Answer:
Step-by-step explanation:
12.9 + 10.2x = 35.1
10.2x = 35.1 - 12.9
10.2x = 22.2
x = 22.2/10.2
x= 222/102 = 111/51

1/3 * x square = 16
x square =16*3
x square =48
therefore x=4 under root 3
Oh ok so square root of 2 is irrational since it goes on and on. square root of 18 is an irrational number too
