Answer:
x =
Step-by-step explanation:
FOIL what is in the parentheses by multiplying terms by -4.
-4(3x) = -12x and -4(2/6) = -4/3
now add these products:
That is the simplified product ^, but assuming you're supposed to set the equation to equal 0...
Set equation to 0 and add the fraction to both sides. Rewrite as
Divide both sides by -12 to get variable, x, alone. Multiplying 4/3 by -1/12 is the same as dividing 4/3 by -12. The negative sign from the -12 make the quotient negative.
x =

Answer:
Step-by-step explanation:
Below is the rectangle in the attachment.
Current scale:
1 cm : 6 inches
If the dimensions of the rectangle is:
Length = a cm
Width = b cm
Using the scale:
Length = a × 6 inches
Width = b × 6 inches
Using the same dimensions of the rectangle is:
Length = a cm
Width = b cm
Using the scale:
Length = a × 12 inches
Width = b × 12 inches
Note that there is an enlargement of the rectangle to form the new rectangle. The length and width of new rectangle drawn will be 2 × the length and width of the rectangle seen below.
10* (1/5)
= 10/5
= 2
The final answer is 2~
Question a: 3cm
question b: 8cm
question c: 12cm
