Answer:
80
Step-by-step explanation:
1.Muliply parenthesis by 2
2x+2-4=4
2.calculate the difference
2x-2=4
3.move constant to the right side and change its sign
2x=4+2
4.add the numbers
2x=6
5. Divide both sides of the equation by 2
x=3
A = (2+9)/2
a = 11/2
a = 5.5

b = (4+4)/2
b = 4

d = √(9-2)²+(4-4)²
d = √7²+0²
r = 3,5
____________________
(x-a)² + (y-b)² = r²
(x-5.5)² + (y-4)² = 3,5²
(x-5.5)² + (y-4)² = 12.25
Example 10 to the 4th power
Answer:
The answer is 5/30
Step-by-step explanation:
The answer is 5/30 because when multiplying a fraction by a fraction you have to multiply the numerator by the numerator and the denominator by the denominator so if you multiply 5 by 1 you get 5 and when you multiply 6 by 5 you get 30 so the answer is 5/30
