(x+5y)(7x-y)
a plastic water pipe is 9m 18cm long if sixty six centmetiers are cut off how long is the pipe left
3x+y=5
x+y=3
(x-2)4-(x+2)4+4x(2x-1)(1+2x)
x - 25 = 20 + 2x
consider the population consisting of 2 4 6 8 and 10. suppose a sample of size of 2
15, 9, 3; 20, 4, 24, 1, ?, 8. Whats missing number
simplify ((6m-8n)/(7qr+7pr))*((9qs+9rs)/(3m^2-4mn))
28x4 ÷ 56x
f(x) = x² - x - 6 / x – 3
