Aconstruction crew must build 3 miles of road. on tuesday, they build 1/4 mile of road. how many miles of road do they still have to build this week

2.25 miles of road they have to build this week

Step-by-step explanation:

Given:

Total distance of the road = 3 miles

Distance constructed on Tuesday = 1/4 mile of road.

To Find:

Miles of road still have to be built this week=?

Solution:

Let the Distance that have  to be built be X

Then,  

X= total distance of the Road – the distance built on Tuesday

X = 3  –  

X = 3 -

X =

X=

X= 2.25  miles

table 1

step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
