The difference is 
.
Step-by-step explanation:
Step 1:
The polynomial 
is subtracted from the polynomial 
.
If we write this as an equation, we get
.
To subtract the polynomials, we group up the terms based on their variables.
In this subtraction, there are two variables i.e. 
and 
and there is one constant term.
Step 2:
The subtraction of the variables; 
.
The subtraction of the variables; 
.
The subtraction of the constants; 
.
So 
.
Rewrite the equations;
m+4n=8
m-n=-2
Eliminating m gives;
5n=10
n=2
Replacing for n in the first equation;
m+4(2)=8
m=8
Answer;
(0, 2)
Answer:
Step-by-step explanation:
S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.
If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle) the hypotenuse of the two triangles will be congruent.
Now, as hypotenuse and one leg are congruent in both triangles, we can apply RHS congruent
