Assuming you mean
(x-2)²=49
sqare root both sides and take positive and negative roots
x-2=+/-7
add 2 to both sides
x=2+/-7
x=2+7 and 2-7
x=9 and -5
The first one would be 1 dash after the last one. The second one would be in the middle of the 3rd and 4th dash, the 3rd would b at 2. The fourth would b slightly after the 1st dash after 3. And the last would be in the middle of the 1st dash after 2.5 and the 2nd

Answer:
The answer is option A : 5%
Step-by-step explanation:
We have the following information in percentage:
Employees taking winter vacation= 75
Employees taking both winter and summer vacation= 40
Employees taking none vacation = 20
We can assume the situation as following:
Winter + Summer - Both + Neither = 100
We get;
75 + Summer - 40 + 20 = 100
So, summer = 45
45 people take vacations in summer. But 40 of them take vacation in winters too.
So, people taking vacations in summer but not winter means summer only.
This is :
%
Therefore, the answer is option A : 5%
Answer:
1. 8y - 9y = -1y
( 8 - 9 = -1)
3. <u>8a</u> - 6 <u>+a</u> - 1
( i have showed the like terms here)
8a - 1a= 7a
-6 - 1 = -7
7a - 7
5. -x - 2 + 15x
( i have showed the like terms here)
-x + 15x = 14x
(x = 1)
14x + 2
7.<u> 8d</u> - 4 <u>- d</u> - 2
( i have showed the like terms here)
8d - d = 7d
-4 -2 = -6
7d - 6
8. 9a <u>+ 8</u> - 2a<u> - 3</u> - 5a
( i have showed the like terms here)
9a - 2a - 5a = 2a
8 - 3= 5
2a + 5
