Answer:
The answer is 40a+14c
Step-by-step explanation:
Step 1: Open the brackets
7a-9c+12a+33c+21a-10c
Step 2: Group all the like terms
Like terms are terms with similar variables, for example;
(7a, 12a, 21a) are all like terms since they have a common variable (a)
(-9c, 33c,-10c) are also like terms since they have a common variable (c)
Step 2: Solve
(7a+12a+21a)+(33c-10c-9c)=40a+14c
The answer is 40a+14c
Answer:
254.47
Step-by-step explanation:
the area of a circle can be found using the formula
pi(radius)^2
in your problem, the radius is 9. Plug it into the equation
pi(9)^2
9^2 is 81
81(pi)
pi is about 3.14
area is 254.47

Answer: A. 0 <------
Step-by-step explanation:
Law of Sines
sinA / a = sinB / b
sin31 / 10 = sinB/ 40
sinB = 40sin31 / 10
sinB = 2.060152299640217
Since 1 is the maximum for sin
the triangle does not exist
A. 0 <------
Answer:
44
Step-by-step explanation:
Answer:
96
Step-by-step explanation:
1.5 X 2 = 3 and 3 X 2 = 6 so you keep multiplying by two until the 7th term
6 X 2 = 12 (4th term)
12 X 2 = 24 (5th term)
24 X 2 = 48 (6th term)
48 X 2 = 96 (7th term)
96 is your answer
