Answer:
5x^2-4+4(x^2)-6x
Step-by-step explanation:
first you need to remove the unnecessary parentheses it should look like this: 5x^2-7-(4(x^2)+6x-3)
then you should calculate the sum it should look like this: 5x^2-4+4(x^2)-6x and that is your answer
The area of triangle B is 10.5 square units.
The area of triangle C is 10 square units.
Step-by-step explanation:
Step 1:
The area of a triangle is half the product of its base length and height.
The base is the lower end of the triangle and its length is called base length.
The length from the base to the highest point on the triangle is the height.
Step 2:
For triangle B, the base extends for a length of 7 units and the height is 3 units.
The area of triangle B
So the area of triangle B is 10.5 square units.
Step 3:
For triangle C, the base extends for a length of 5 units and the height is 4 units.
The area of triangle C
So the area of triangle C is 10 square units.
Answer:
Step-by-step explanation:
7p - 3p - 3 = -2p + 33
4p - 3 = -2p + 33
6p - 3 = 33
6p = 36
p = 6
A frequency distribution table is a table that summarizes data in two columns.
The result does not appear to have a normal distribution.
<h3>How to construct the frequency distribution table</h3>
From the dataset, we have the following classes using 5 classes with a lower class limit of 119.4 and a class width of 0.2 volts
119.4 - 119.6, 119.7 - 119.9, 120.0 - 120.2. 120.3 - 120.5. and 120.6 - 120.8
So, the frequency distribution table is:
<u>Class Frequency</u>
119.4 - 119.6 4
119.7 - 119.9 10
120.0 - 120.2 6
120.3 - 120.5 5
120.6 - 120.8 0
The result does not appear to be normal.
This is so, because the frequency table do not go in form of a bell shape
