Answer:
5n^2 - 3n - 8
Step-by-step explanation:
4n.5n - 4n.8 + 4.5n - 4.8
= 20n^2 - 32n + 20n - 32
= 20n^2 - 12n - 32
= 4 ( 5n^2 - 3n - 8 )
= 5n^2 - 3n - 8 [ answer ]
What is the solution for the equation?
14.8 = n minus 0.3

What is the value of x?
40"
X
55
O A. 85°
O B. 105°
O c. 75°
D. 95°
Answer:
A. 85°
Step-by-step explanation:
By interior angle sum theorem of a triangle.
x = 180° - ( 40° + 55°)
x = 180° - 95°
x = 85°
Answer:
A. 85
Step-by-step explanation:
Youd do 40+55 and that equals 95 and then since a triangle qdds up to 180 degrees, 180-95=85
Determine the measure of the vertical angle. Find x. Step by step ? If not that’s fine.

Four times a number reduced by seven equals 42
Question 7 options:
4x - 7 = 42
4x + 7 = 42
42 - 4x = 7
7x + 4 = 42
What is the slope of the line that contains these points? x=9,13,17,21 and y =-24,-21,-18,-15
Match the word to its description.
The most frequent value = mode
The middle value = median
The average = mean
The difference between the lowest and highest value = range
Answer:
Mode is the most frequent value
Mean is the average
Median Is the middle value
Range is the difference between etc...
through: (1, 2), parallel to y = 3x + 1
Answer:
Step-by-step explanation:
so just use the slope of the equations m = 3 and plug in your points
to the point-slope formula
y-2=3(x-1)
y = 3x-3+2
y = 3x -1
now you have an equation that gives you a parallel line to the first, but moved down by 2 :)

Чx-2(x+4)=22
How do I do this
Answer:
x = 7
Step-by-step explanation:
4x - 2(x + 4) = 22
Distribute:
4x - 2x - 8 = 22
Combine like terms:
2x - 8 = 22
Simplify and solve:
2x = 14
x = 7
Answer:
4x-2x-8=22
2x-8=22
2x=30
x=15
