Answer:
R=50 degrees
Step-by-step explanation:
All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:
180= (3x+5) + (11x-1) + (5x+5)
You then combine like terms:
180= (3x+11x+5x) + (5-1+5)
180= 19x+9
Then, subtract 9 from 180:
171= 19x
Then, divide 171 by 19:
9= x
Finally, you plug the value of x into the equation representing angle R:
5 x 9 + 5
45 + 5
50
I am confused what are you asking?
Hello,
3x³a + 3x²a²
⇒ <u>common factor :</u> 3x²a
3x³a + 3x²a²
= 3x²a * x + 3x²a * a
= 3x²a(x + a)

Find A cup(B cap C) . A = \{1, 4, 6, 7\}; B = \{3, 4, 5\}; C = \{2, 4, 8\}; \{1, 4, 6, 7\} 4 } \{1, 2, 3, 4, 5, 6, 7, 8\}
Inessa05 [86]
The only common element between B and C is 4, so B ∩ C = {4}.
4 is also already contained in A, so B ∩ C is a subset of A, and thus
A U (B ∩ C) = A = {1, 4, 6, 7}
Answer:
For mean
To show the mean of height measures for 40 students, you need to write-out exactly 40 heights into a calculator and add them up.
Then divide that total number by 40.
Step-by-step explanation:
Eg for 4 students
5 , 5.1, 5.2, 5.7 = 21ft
21/4 = 5.25ft.
Apply the same method but use 40 measures in addition for calulator or long addition. Then divide by 40.
