Answer:
55.7 in.
Step-by-step explanation:
I assume the figure is a rectangle and a half circle.
The three sides of the rectangle that need to be added toward the perimeter measure 15 in., 10 in., and 15 in.
Then you need the circumference of the half circle which has a 10-inch diameter.
circumference = (pi)d
circumference = 3.14 * 10 in. = 31.4 in.
We only need half the circumference, so we have 31.4 in./2 = 15.7 in.
Now we add the three sides of the rectangle listed above and the circumference of the half circle.
perimeter = 15 in. + 10 in. + 15 in. + 15.7 in.
perimeter = 55.7 in.
Answer:
x<6
Step-by-step explanation:
x/2 < 7-4
x < 3*2
x<6
First one single solution second no solution 3rd one single forth one infinity and last 2 are single and infinity

if you get a positive value, that means 2 real solutions
if you get 0, means 1 real solution only
if you get a negative value, is an imaginary root solution, same as saying no solution.
