The 2 outside the brackets means that everything within the brackets needs to be multiplied by 2
Multiply 200 by .15, since 15% is .15 as a decimal. 200 x .15 = 30. This means that his health care rate will increase by $30 next year.
Answer:
1. 12/1= rate of change

Formula: y2-y1/x2-x1
90-30/6-1
60/5
12/1= rate of change
hope its right
Hi, We have a isosceles triangle.
Then,
There is two angles = (2x +2)°
As the sum of angles = 180° To the any triangle.
Then we wiil stay with:
(2x+2)° + (2x+2)° +(3x+1)° = 180°
Canceling °
2x+2+2x+2+3x+1=180
7x +5 = 180
7x = 180-5
7x = 175
Passing 7 dividing 175
x = 175/7
x = 25
This would be your answer!
