Answer: P = 2
Step-by-step explanation:
18 = 2(p+7)
18 = 2(2P+14)
-14 -14
4 = 2P
2=P
Answer:
no
negative 4 i think im dumb tho
Step-by-step explanation:
For this case we have by definition, that the perimeter of the figure will be given by the sum of its sides, that is:

We add similar terms:

Thus, the correct option is option b. That is, 
Answer:

The tangent = -2/4 = -1/2
The length of the hypotenuse = sqrt20 = 2 sqrt5
sine = 2 / 2 sqrt5 = 1 / sqrt5
cosine = -4 / 2 sqrt5 = -2/sqrt5
Answer:
1. 6pi or 18.84cm
2. 20pi or 62.8cm
3. 13pi or 40.82cm
4. 9.5pi or 29.83cm
5. You calculate the circumference of a circle with the expression 2pi(r). r stands for the radius. You can also use pi(d), or pi x diameter.
7. You would use 2pi(r) to find the circumference of a circle when given the value of the circle's radius.
8. You would use pi(d) to find the circumference of a circle when given the value of the circle's diameter.
