Answer:
Note :
The perimeter is : AB + BC + CA
AB =√((XB - XA)² + (YB - YA)²) = √((16-2)²+(2-8)²) = √(12²+6²) = √(144+36)=√180
AB = √(36×5) = 6√5 units
same method for : BC ; CA ..........
Answer:
Perpendicular with respects to what?
You can't find it with only a point, you also need a slope to know which line is which.
There are an infinite number of lines that go through any point. Each has a slope, without slopes, we cant solve such a question.
It's line asking, how old is Jane's dog?
Who knows man? There's like thousands of Janes, which one is the one?
Answer = 2 plus 5 times n
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
x < -1
The solution is the interval ----> (-∞,-1)
All real numbers less than -1
On a number line the solution is the shaded area at the left of x=-1 (open circle)
using a graphing tool
see the attached figure
What are we multiplying exactly?
