Answer: A. 2x(x²)+2x(5x)+2x(-2xy)+2x(-10y)
B. 2x(x²+5x-2xy-10y)
Step-by-step explanation:
note: x*x means x times x
remember distributive and reverse it
ab+ac=a(b+c)
a is gcf
factor each
2x³=2*x*x*x
10x²=2*5*x*x
4x²y=2*2*x*x*y
20xy=2*2*5*x*y
gcf=2*x or 2x
2x³+10x²-4x²y-20xy=
2x(x²)+2x(5x)+2x(-2xy)+2x(-10y)=
2x(x²+5x-2xy-10y)
A is 12 because 4x4=16 so then you would multiply 3x4=12
Answer:
22
Step-by-step explanation:
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
Answer:
45 degrees
Step-by-step explanation:
Answer:
or 
Step-by-step explanation:
The question is
Find the slope intercept form of the line parallel to the line 5x+8y=120 passing through (4,5)
step 1
Find the slope of the given line
we have

isolate the variable y


The slope of the given line is m=-5/8
step 2
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the parallel line to given line is m=-5/8
step 3
Find the equation of the line into slope intercept form
The equation of the line into slope intercept form is equal to

we have
m=-5/8 and point (4,5)
substitute and solve for b
