Answer:
x2 - 4x - 21
Step-by-step explanation:
Area = (x -7 )(x +3)
= x*x - 7*x + x*3 - 7*3
=x2 - 4x - 21
Answer:
Step-by-step explanation:
Answer:
4. About 2,700 in2
Step-by-step explanation:
The area of a circle (
), measured in square inches, is directly proportional to the square of its diameter (
), measured in inches. That is:
Where 
is the constant of proportionality, dimensionless.
In consequence, the following relationship between circles A and B is obtained:
The area of the circle B is now cleared:
Given that 
, 
and 
, then:
Therefore, the correct answer is 4.
Answer:
tbh i like the first one its so simple but like so nice at the same time
Answer:
Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1. Reflection A reflection is an example of a transformation that flips each point of a shape over the same line.
