Answer:
The side length is multiplied by 
Step-by-step explanation:
we know that
The area of the original square is equal to
If the area is doubled
then
The area of the larger square is
Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of the larger square
y ---> the area of the original square
so
we have
------> scale factor
therefore
The side length is multiplied by
Perimeter is all the sides added up together.
Divide 16 by 2, so that you can get just a measurement of the length and the width.
16/2 = 8
Since the length is 5.25, subtract that by 8.
8-5.25 = 2.75
The width of the phone is 2.75 inches.
Answer:
D. (x-5)^2 = 36
Step-by-step explanation:
If you add 11 to the given equation, you get ...
x^2 -10x = 11
Then you can add the square of half the x-coefficient to complete the square.
x^2 -10x +25 = 11 +25
(x -5)^2 = 36 . . . . simplify to the appropriate form
