Combine like terms by adding their FACES (Coefficients)
1) 4c² - 4
2) 20m^4 + 6m
3) -6a³ - 19a² + 8a - 10
4) -10a² - 2b + 3ab³ + 4a²b² -5b^4 - 9a²b² - 12a³b + 15ab³ = -10a² - 2b + 18ab³ - 5a²b² - 12a³b - 5b^4
5) 5a³ - 5a²
Answer:
Option A
Step-by-step explanation:
To find all missing sides of a right triangle we use the sine, cosine or tangent ratio as below,
sinθ = 
cosθ = 
tanθ = 
Now we take an angle measuring 60°
sin(60°) = 

y = 4√3
tan(60°) = 
√3 = 
x = 2√3
Therefore, Option A will be the correct option.
Step-by-step explanation:
a. 8,435 is divisible by 5
b. 981 is divisible by 3 and 9
So, the next two numbers are 55 and 89
So,
1+1=2
1+2=3
2+3=5
Starting at the 1,1 add them together to get the next number which is 2. Then 1,2 add 1+2 to get the next number which is 3. Next, 2,3 add 2+3 to get the next number which is 5
I hope you understand that. I tried to explain it at the best of my ability
