Answer:
Part A: OC. 16π square inches
Part B: OC. 36π square inches
Step-by-step explanation:
<u>Part A:</u>
Given
Diameter of circular picture = d = 8 inches
We need to find the radius first to find the area
So,
Rdius = r = d/2 = 8/2 = 4 inches

Therefore, option C is the correct answer..
<u>Part B: </u>
As two inches frame is added around the picture, the diameter will become 8+4 =12 inches
The new radius will be:
r = 12/2 = 6
So,

Therefore, option C is correct ..
Answer:
x > 1
Step-by-step explanation:
2x+5>7
move constant to right
2x>5-7
subtract 7 and 5
2x>2
divide both sides
x > 1
Answer:
2. y = -9x + 7
2. y = 3x - 2
3. y - 6 = 10(2x - 1)
1. 5x + 2y = 10
4. 5x = 3y + 9
3. y + 2 = 6(x - 4)
Step-by-step explanation:
Answer:
|x| + 6
Step-by-step explanation:
For F= (x) substitute x with g(x) = |x| + 6
Answer:
