The answer to this question is true. The equation (x-h)^2+(y-k)^2 = r^2 represents a circle with a center at (h,k). Taking (h,k) = (-2,2) and r = 3 results in (x+2)^2 + (y-2)^2 = 9. A negative subtracted by a negative is a positive.
Answer: Each pen cost $3.12
Step-by-step explanation:
If you divide 31.20 by 10 you will get 3.12. Each pen costs the same amount so that amount ten times would equal $31.20. To find out how much one pen costs you need solve for only one out of these ten pens which is why you divide.

Step-by-step explanation:
Answer: <u>942.48 </u>
<u></u>
Step-by-step explanation:
First we find the area of the base (the circle) the formula for that is
the radius is 5 because it is half the diameter.
so our base is <u>78.54</u>
then we multiply that by the height
so 78.54 times 12 = <em><u>942.48</u></em>
Answer:
7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
Step-by-step explanation:
Multiplying the positive whole number 7 by 3 and adding 1 will get:
(7 × 3) + 1 = 21 + 1 = 22
Multiplying the positive whole number 7 by 2 and adding 8 will get:
(7 × 2) + 8 = 14 + 8 = 22
Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
