Answer:
A. 66
Step-by-step explanation:
Team A scored:
78+66=144
78-66=12 so Team A scored 12 fewer points than Team B
Yes they are , since they are very common in ones body
Answer: 82 sq. units .
Step-by-step explanation:
Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.
Then we plot them on graph ( as provided in attachment)
Length = AB
units [By distance formula :
]
units
Width = BC =
units

Area = length x width
= 
Hence, the area of the rectangle is 82 sq. units .
If you use slope-intercept form, Y =mx+b
m is equal to the slope,
and b is the y intercept.
Y= (1/2)x+ (-1)
or
Y = (1/2)x-1
x=-
or
x=-3.666666666666666666666666666666666666666666666
