Answer:
Step-by-step explanation:
The first step is to determine if some of the terms can be combined (added), so you have to look for like terms (like terms have the same variables with the same exponent).
We have the expression:
We can see that there are two elements that contain x ( and
) , this means that they are like terms and we can add them:
⇒
and this would be the final result, since there are no more like terms in this expression. The answer is D.

Answer:
9 labours
Step-by-step explanation:
In order to solve this, we must know which kind of proportionality is this. There are two types of proportions, direct and indirect/inverse proportions. In direct proportion, if one quantity increases, the other quantity also increases.
In indirect proportion, if one quantity increases, the other decreases and vice versa.
As per this question, we know if the number of labour increases, the number of days to complete a work decreases, thus proving that this is an indirect/inverse proportion.
6 labours => 12 days
x labours => 8 days
Since its an inverse proprotion, multiply 6 with 12, and x with 8.
8x = 6 × 12
x =
∴ x = <u>9 labours</u>
