Answer:
The answer is 12 I believe
Step-by-step explanation:
You just want to add all the numbers you already have and subtract that with your perimeter to get 12. So 7+15+16=38; 50-38=12.
EG is 12.2 because the line down the middle is called a bisect which means that it splits the triangle right down the middle making each side equal. so if you do 6.1 x 2 or just add 6.1+6.1 which is the same thing lol, you will have your answer
The unknown number is X;
x/6+2=9;
X/6=7;
X=42;
The answer is 42
Answer:
Step-by-step explanation:
make one side equal to zero:
find two factors that multiply to -36 and add to -5 (-9 & 4)
factorise
