Jan is enlarging the sketch shown on a photocopier. which could be the dimensions of her enlargement?

the figure shows a rectangle. the horizontal length of the rectangle is labeled as 3 inches and the vertical length of the rectangle is labeled as 2 inches.

a.
4 inches × 5 inches

b.
5 inches × 6 inches

c.
7 inches × 10.5 inches

d.
8 inches × 9 inches

C. 7 inches × 10.5 inches

Step-by-step explanation:

Jan is enlarging the sketch shown on a photocopier. The figure shows a rectangle  3 inches long and  2 inches wide.

Hie enlarged rectangle must be similar to the given one. Similar rectangles have propotional sides, so

the width of the new rectangle = 2x inches

the length of the new rectangle = 3x inches.

Check all options:

A. If 2x = 4, then x = 2 and 3x = 6 - false

B. If 2x = 5, then x = 2.5 and 3x = 7.5 - false

C. If 2x = 7, then x= 3.5 amd 3x = 10.5 - true

D. If 2x = 8, then x = 4 and 3x = 12 - false

step-by-step explanation:

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".
