Answer : x = ± 1 4x2 - 30 = 34 : 4x2 = 34 - 30 = 4 4x2 = 4 : x2 = 1 therefore x = √1 = ± 1
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
6(4+y)
4x² - 30 = 34 4x² = 34 + 30 4x² = 64 4x = √64 4x = 8 x = 8 ÷ 4 x = 2

120 ÷ 30 = 4
30 can go into 143 4 times because 30x4=120

It goes 30 times, with a remainder.
Exactly 30 times
5
30.75 times or 30 times with a remainder of 3.
6 times, there is also a remainder which is 4.
4 with remainder 1.
