The perimeter is 42 cm.

Using the expression 2l + 2w, it would be 2(18) + 2(3)

2(18) = 36

2(3) = 6

36 + 6 = 42

At a store, markers are sold in packages of 12 and pens are sold in packages of 8. What is the least amount of markers and pens
liubo4ka [24]

Given:

Markers are sold in packages of 12 and pens are sold in packages of 8.

To find:

Least amount of markers and pens Rick needs to buy to have an equal number of markers and pens

Solution:

To find the least amount of markers and pens, we need to find the LCM of 12 and 8.

Prime factors of 8 and 12 are

8=2\times 2\times 2

12=2\times 2\times 3

To find the LCM, multiply all factors but the common factors are included only once.

LCM(8,12)=2\times 2\times 2\times 3

LCM(8,12)=24

Therefore, the least amount of markers and pens Rick needs to buy to have an equal number of markers and pens is 24.

I think it is self explanatory. Good luck! And remember you can always use long division if you don’t prefer synthetic division. Just rewrite the coefficients in the proper equation. :)
