Answer:

Step-by-step explanation:
2(x^2 + 10x + 25) + 3
2x^2 + 20x + 50 + 3
2x^2 + 20x + 53
Answer:
18pi, or 56.52
Step-by-step explanation:
To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle
However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:
(pi x radius^2)/2 = area of semi-circle
(pi x 6^2)/2 = area of semi-circle
(36 x pi)/2 = area of semi-circle
18 x pi = area of semi-circle
18 x 3.14 = area of semi-circle
56.52 = area of semi-circle
Answer:
(-7, -3)
Step-by-step explanation:
Do it in two steps:
a) First mirror point (7,3) in x-axis gives (7, -3).
Then the next step...
b) ...mirror point (7, -3) in y-axis gives (-7, -3)
Please understand that the outcome is the same, if you first mirror in y-axis and then mirror in the x-axis.
Just to demonstrate this:
a) If you irst mirror point (7,3) in y-axis gives (-7, 3).
Then the next step...
b) ...mirror point (-7, 3) in x-axis gives (-7, -3)
