Answer:
3/40
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 9 and 120 is 3
Divide both the numerator and denominator by the GCD
9 ÷ 3
120 ÷ 3
Reduced fraction:
3/40
Answer:
Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4… Integers include all whole numbers and their negative counterpart e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… Where a and b are both integers.
Step-by-step explanation:
Step-by-step explanation:
log <base a> b = x
means
a^x = b
So
3^2 = x^2+7x+21
x^2 + 7x + 21 - 9 = 0
x^2 + 7x + 12 = 0
(x+3)(x+4)
x = -3 or -4
