Coordinates of the center: ( 4, 4 )
The radius: r = 7 - 4 = 3
The equation of a circle:
( x - 4 )² + ( y - 4 )² = 3²
x² - 8 x + 16 + y² - 8 y + 16 = 9
x² + y² - 8 x - 8 y + 32 - 9 = 0
Answer:
A ) x² + y² - 8 x - 8 y + 23 = 0
Answer:
5' 10"
Step-by-step explanation:
We subtract by converting into one measurement. We will choose inches.
8'4"= 96"+4"=100" since 8' has 8(12) inches
2'6"=24+6=30" since 2' has 2(12) inches
Subtract.
100"-30"=70"
We convert back into feet and inches by dividing by 12.
70/12= 5' 10"
The answers of the product is 1.8 * 0.63 = 1.134
Answer:
3x + 21
Step-by-step explanation:
(3)(x+7)
Now, we distribute the 3 in each term of (x+7)
So, 3*x = 3x and 3*7 = 21.
So our resulting term would be 3x+21.
