Using (n-2)180 to find total number of degrees in a 5-sided shape
n= number of sides
(5-2)180=540degrees
So to find x, 100+160+80= 340
540-340=200
So 8x+8+5x+10=200 and solve for x
2. All real numbers greater than 0
Answer:
Option C. 0≤x≤25
Step-by-step explanation:
we know that
The function f(x) of the graph is a vertical parabola open down
If the function is at least 300
then
The solution is the shaded area above the solid line f(x)=300
In the graph plot f(x)=300 and find the value of x
The values of x are
see the attached figure
therefore
The interval is ------> [0,25]
All real numbers greater than or equal to zero and less than or equal to 25
