Answer:its 52
Step-by-step explanation: 2*2*1+ 2*8*2+ 2*2*1+ 4+36+ 4= 52
From pt 1 to pt 2 there is a three unit change, from pt 2 to pt 3 there is a 3 unit change, from 3 to 4 there is a 5 unit change, and from 4 to 1 there is a 3 unit change. Add those together 3+3+3+5= 14 units is perimeter
To find area: look at image. answer is 30 units
Let the numbers be a and b and b>a
2a=3b and 3(b-a)=2(b-a)+13
Solving the first for a:
2a=3b
a=3b/2, now using this value of a in the second equation gives you:
3(b-3b/2)=2(b-3b/2)+13 upon performing indicated operations.
3b-9b/2=2b-6b/2+13 making all terms have a common denominator of 2
(6b-9b)/2=(4b-6b+26)/2 multiplying the whole equation by 2
6b-9b=4b-6b+26 combining like terms
-3b=-2b+26 adding 2b to both sides
-b=26 dividing both sides by -1
b=-26, since a=3b/2
a=3(-26)/2
a=-39
So the numbers are -39 and -26
check...
2a=3b becomes:
2(-39)=3(-26)
-78=-78
3(b-a)=2(b-a)+13 becomes:
3(-26--39)=2(-26--39)+13
3(13)=2(13)+13
39=26+13
39=39
correct :P
Answer: -2
Step-by-step explanation:
Because I know
Answer: 1/4
Step-by-step explanation:
We can actually write an equation to find what should be added to get -1.

We get this equaiton because the problem asks what should be added to -5/4 to get -1. We put x in place to see what number fits. X is being added to the -5/4.
