For this case we have the expression:
"the square root of 4" is represented algebraically as:
Then, we can express the given statement as:
They are similar terms, we can subtract:
By definition of power properties we have that:
Then the expression is reduced to:
Answer:
For this case we have the following data:
The original dimensions of the drawing are:
If the copier zoom is at 120%, we can find the new dimensions of the drawing by making a rule of three:
Width:
3 ----------> 100%
x ----------> 120%
Where x represents the new width of the drawing:
Long:
5 ----------> 100%
y ----------> 120%
Where y represents the new long of the drawing:
Thus, the new dimensions are 3.6 cm wide and 6 cm long
Answer:
the longer dimension of the new drawing is 6cm
