The standard deviation of 36,18,12,10 and 9 is 10
Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + 2x + 2 + 3x + 4 = 180, that is
6x + 6 = 180 ( subtract 6 from both sides )
6x = 174 ( divide both sides by 6 )
x = 29
42 divided by 7 =6 then u times 5 and 6 together . Then times 2 by 6 together so the answer is 30:12
5/8 * 4/5
= 1/8 * 4/1
= 1/4 * 2/1
1/2 * 1/1
Final answer = 1/2

the first onewould evaluate to 4x²
the 2nd one would just be -2x²
