Based on the given summation notation, the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n
<h3>How to determine the summation expression?</h3>
The expression is given as:
43Σn=1(3+9n)
As a general rule, if a summation notation is represented using the following expression
Σ(a + bn)
The equivalent expression of the above summation notation is
Σa + bn
Where the variable a is a constant in the expression
This means that:
Σ(a + bn) = Σa + bn
Using the above equation as a guide, we have the following equivalent equation
43 Σ n=1 (3+9n) = 43 Σ n=1 3 + 43 Σ n=1 9n
Hence, based on the given summation notation; the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

Answer:
Mind if ya brainiest meh
Step-by-step explanation:
The volume of the hemisphere is 1071.78 ft^3
5x and 6x are like terms because they are both followed by an x. 20 and -13 are also like terms. For they have nothing behind them. Hope this helps!

Answer:
X = -4, y = 3
Step-by-step explanation:
Plug it in
-3x - 3(-5x - 17) = 3
-3x + 15x + 51 = 3
12x + 51 = 3
12x = -48
x = -4
plug it in to find y
Y = -5(-4) -17
y = 20 - 17
y = 3
