The dilation of rectangle ABCD to create rectangle A'B'C'D' would change the size of the rectangle
The dilation rule is: (x,y) -> k(x,y)
<h3>How to determine the rule of dilation?</h3>
The coordinates of C' is given as:
C' = (4.5, 4.5)
The coordinate of point C is not given.
So, I will apply a general rule
The general rule of dilation is:
(x,y) -> k(x,y)
Where k represents the scale factor.
Assume that k = 3, the the rule would be
(x,y) -> 3(x,y)

Answer:
1.
2.
Step-by-step explanation:
1. The first thing to do to factor the expression is to take the expression (a + 3) as a common factor with its lowest exponent.
Then the expression. remains as:

Answer:
Step-by-step explanation:
You are told that the diameter of a penny is 3/4 of an inch. The decimal equivalent is 0.75 inches.
r = d/2
r = 0.75/2 = 0.375 inches.
Area = pi r^2
pi = 22/7
r = 0.375
Area = 22/7 * 0.375^2
Area = 22 * 0.375^2/7
Area = 3.094 / 7
Area = 0.44196
If you retain this in fractions then the answer is 99/224
=======================
Area = 22 / 7 * 3/8 * 3/8
Area = 22/7 * 9/64
Area = 198 / 448 Both can be divided by 2
Area = 99 / 224
I did it the top way because I think it is the most common way to solve this question. Your teacher may not agree, but you should see both ways.
Area = 3.094 square inches.
Fraction = 3.
