Answer:
7c + 6s - 63
Step-by-step explanation:
7c - 18 + 6s - 45
Combine like terms
7c + 6s - 63
Answer:
9 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , so
exterior angle + 140° = 180° ( subtract 140° from both sides )
exterior angle = 40°
The sum of the exterior angles of a polygon = 360°
Dividing sum by the measure of 1 exterior angles gives number of sides
number of sides = 
= 9
Answer:
- using the rule given: 2.5
- using an exponential rule: 7
Step-by-step explanation:
Evaluating the linear rule given, for n = 1, we have ...
a1 = 7(1/2)(1) -1 = 7/2 -1 = 5/2 = 2.5
_____
We suspect you may intend the exponential function ...
an = 7(1/2)^(n-1)
Then, for n = 1, we have ...
a1 = 7(1/2)^(1 -1) = 7(1) = 7 . . . . the first term is 7
_____
When writing an exponential expression in plain text, it requires the exponential operator, a caret (^). If the exponent contains any arithmetic, as this one does, it must be enclosed in parentheses.
