5. suppose you are making a scale drawing. find the length of each object on the scale drawing with the given scale. then find the scale factor. a. a room 14 feet long; 1 inch = 6 feet b. a tower 40 meters tall; 0.8 centimeter = 1 meter.

a) a room 14 feet long; 1 inch = 6 feet

To find the length of each object on the scale drawing we make a proportion using the given information

6 feet = 1 inch , 14 feet = x inches

=

=

Cross multiply it,

14 = 6x

divide by 6 on both sides

So x = 2.3 inches

b) a tower 40 meters tall; 0.8 centimeter = 1 meter.

Lets make a proportion using given information

1 meter =0.8 centimeter , 40 meters = x centimeter

40 * 0.8 = 1x

x= 32 centimeter

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".
