Answer: 1/3
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal.
For example, if slope of line A is a/b, then slope of line B which is perpendicular will be -b/a.
Substitute 1 and 3 for a and b. Apply the formula and get 1/3.
Answer:
x=3 , x=-3

Answer:
25
Step-by-step explanation:
add the two sides which are 6 and 6, then find the circumference of one of the circles and thats it, the reason why you only need one is because both of those circles are halfs, so they make one circle up, so its 6+6, then the circumference is 12.5667 so its 12+12.5667 which is 24.5667 which rounds up to 25.
