We can expand this expression using foil method (multiply first terms, outer terms, inner terms then last terms together):
<span>(x+4)(x+6)
x^2 + 6x + 4x + 24
combine like terms
x^2 + 10x + 24
This is also the final simplified expression. It cannot be further expanded or simplified. Foil method is the easiest way to expand expressions.</span>
Answer: 16,000 students
Step-by-step explanation:
8/20 = x/40,000
20 * x = 8 * 40,000
x = (8 * 40,000)/20
x = 16,000 students
Answer:
71/2000
Step-by-step explanation:
Recall that 1 tonne = 1000 kg
In other words, to convert from tonnes to Kg, multiply the quantity in tonnes by 1000. Going by the above,
2 tonnes = 2 * 1000
= 2000 kg
As such, 71 kg as a fraction of 2 tonnes will be
= 71/2000
This will have no unit as the two quantities are in Kg.
