Answer:
Area is (x² - 9) units squared.
Step-by-step explanation:
• from difference of squares quadratic property:

→ a is x
→ b is 3
• Therefore:

Answer:
x=5/2
Step-by-step explanation:
The x-value of a midpoint is the average of the x-values of the ends.
The y-value of a midpoint is the average of the y-values of the ends.
The x-value of the end at b is 20 and it's 18 at the middle.
x has decreased by 2 in the course of 1/2 of the line.
So it will decrease another 2 during the other half of the line.
The x-value at the other end, at a, then, is 16.
The y-value of the end at b is 4 and it's -2 at the middle.
y has decreased by 6 in the course of 1/2 of the line.
So it will decrease another 6 during the other half of the line.
The y-value at the other end, at a, then, is -8.
The other end of the line, at a, is at (16, -8) .
The sum of the coordinates at a (p+q) is 8 .
Answer: Id personally say D
Step-by-step explanation:
Let’s turn the mixed number into a fraction
3/2 x 1/2
Multiply across
3/4
