Answer:
26.14
Step-by-step explanation:
For the triangles: 3*4=12
For the circle: 28.27/2=14.135
12+14.135=26.135
~26.14
Answer:
x=35
Step-by-step explanation:
When a is parallel to b, the two angles will add to 180
x+ 3x+40=180
Combine like terms
4x+40 =180
Subtract 40 from each side
4x= 180-40
4x= 140
Divide by 4
4x/4 = 140/4
x=35

A sample of n=8 scores has a mean of m=12. What is the value of ∑x for this sample
Answer: We are given the mean of 8 scores is 12.
We are required to find the sum of these 8 observation's, 
We know that:

We are given:




Hence, sum of 8 observation's, 
Answer:
15x² - 3x - 7
Step-by-step explanation:
(12x² + 2x) - (-3x²+ 5x + 7)
First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:
12x² + 2x + 3x² - 5x - 7
Add like terms
12x² + 3x² + 2x - 5x - 7
15x² - 3x - 7
