Hi there!
Let's break this down:
Two times a number = 2n
Increased by 5 = + 5
is 15 - = 15
Total equation:
2n + 5 = 15
Solving:
2n + 5 = 15
2n = 10
n = 5
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
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
Answer:
Positive
Step-by-step explanation:
If you multiply both negative, it will always result to positive.
Rule:
+ × + = +
+ × - = -
- × + = -
- × - = +
÷
= 7, but Im not 100% sure if thats right. You should pick someone else's answer.
