Ivan is painting 3 walls in his living room. each wall measures 9 3/4 feet tall by 14 1/4 feet wide. ivan needs to estimate the total area he will paint in order to determine the amount of paint to purchase. which expression best represents the estimated area in square feet that ivan will paint?

The estimated area is

Step-by-step explanation:

we know that

To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3

step 1

Convert the dimensions to an improper fractions

step 2

Find the area of one wall

step 3

Multiply the area of one wall by 3

step 4

Convert to mixed number

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".

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
