Answer:
The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.
Answer:
-5
Step-by-step explanation:
First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)
This would look like:

This means the slope is -5.
Parallel lines always have the same slope, so the slope of the parallel line is also -5
Answer: 110-35=x
answer: 7 minutes
I came here to find the answer to this proble but since no one answered I’ll just put the answer that I got.
Step-by-step explanation:
The 5 is the coefficient...

No real solutions, because for all real numbers the square of number is greater or equal 0.
