For one set the two equations equal to eachother and solve from there. 2 is 45
For three set the two equations equal. Same for four
This equation does not have a solution. You can see this through the work below.
4m-4=4m
-4m -4m
-4≠0
There is no solution because 0 does not equal -4.
Additive inverse: In math the additive inverse of "a" is the number when added to "a" should give zero (a) + (-a) = 0
So the sum of a number and its additive inverse is always equal to zero
Answer:
0.1
Step-by-step explanation:
2x*4 = 0.8
x = 0.1
Perimeter is the sum of all sides, thus 4 * 2x.
