Answer:
x(4x + 3)(4x + 1).
Step-by-step explanation:
16x^3 + 16x^2 + 3x
First take out the x:
= x(16x^2 + 16x + 3)
= x(16x^2 + 4x + 12x + 3)
= x(4x(4x + 1) + 3(4x + 1))
= x(4x + 3)(4x + 1) (answer).
Answer: £ 81.38
Step-by-step explanation:
Given: On Monday,
5 builders took
hours ( i.e.
hours ) to build a wall.
On Tuesday, only 2 builders were available.
As workers are inversely proportional to the time if the job remains constant.
Inverse variation equation : 
Let x be the time taken by 2 builders, then


So, 2 builders will take 8.75 hours.
Each paid £9.30 for each hour.
Then, each builder will be paid for the work completed on Tuesday = £9.30 x 8.75
≈ £ 81.38
Hence, each builder will be paid £ 81.38 for the work completed on Tuesday .
