What factor is common to all the expressions x2 - x, 2x2 + x - 1 and x2 - 1?
x
x + 1
x - 1
No common factor
(2x - 1)
Correct answer is D
x2 - x = x(x - 1)
= 2x2 + x - 1
= (2x - 1)(x + 10
x2 - 1 = (x + 1)(x - 1)
No factor
Make c the subject of formula v = 1 - \(\frac{a}{5}\)(b + \(\frac{3c}{7}\))
[\(\frac{7}{3}\) + \(\frac{5}{a}\)(v - 1)] + b
[\(\frac{7b}{3}\) + \(\frac{5}{a}\)(v - 1)]
\(\frac{7}{3}\)[b + \(\frac{5}{a}\)(v - 1)]
\(\frac{7}{3}\)[b + \(\frac{5v - 1}{a}\)]
Correct answer is A

Simplify \(\frac{log_{10}8}{log_{10}4}\)
log102
log104
\(\frac{3}{2}\)
2
None of the above
Correct answer is C
\(\frac{log_{10}8}{log_{10}4}\) = \(\frac{log_{10}2^3}{log_{10}2^2}\)
= \(\frac{3 log_{10}2}{2log_{10}2}\)
= \(\frac{3}{2}\)
N216
N200
N184
N144
N100
Correct answer is C
10% of 400 = N40, Remainder = N360 40% of 360 = N144 Altogether they 144 + 40 = N184
