Answer: 12 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is 180(n-2), where n is the number of sides
9x+12=5x+4
9x-5x=12-4
4x=8
x=8/4
x=2
Answer:
The answer is B
Step-by-step explanation:
Answer: two equations represent the situation are
y = 3x and y = x + 4
Step-by-step explanation:
The smaller number was represented by x and its values on the x coordinate.
The larger number was represented by y and its values on the y coordinate.
The larger number is equal to 3 times a smaller number. This means that
y = 3x
Also, the sum of the smaller number and 4 is the larger number. This means that
y = x + 4
Answer:
392π
Step-by-step explanation:
Equation is 1/3(piR^2)*h
Radius is 7, 7 squared is 49.
1/3(49π)(24)
392π
