Question 4, noah has 12 yellow square cards and 18 green ones all the cards are the same size he would like to arrange the square cards into two rectangle one of each color he wants both to be as tall as possible. what is the tallest possible height for the two rectangles. greatest common factor least common factor.

question 5, explain how you know which problem(s) involves finding the greatest common factor

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

8
