Answer:
Step-by-step explanation:
Multiply the first bracket by 13
Multiply the second bracket by -4
13(6-x)-4(3x+12)=0
78-13x-12x-48=0
30-25x=0
-25x+30-30=0-30
-25x=-30
Divide by -25 for -25x and-30
x=30/25 reducing: 6/5= 1 1/5
Answer can be 30/25 or 6/5 or 1 1/5
Answer:
12.76
Step-by-step explanation:
This is much easier to solve if you draw it out on a graph. The perimeter is the sum of all the sides. I used the Pythagorean theorem to find the hypotenuse.


answer is 13 but I can't understand the question
I think there is no correct answer in this question!
you can solve this by analytic geometry rules easily!!
A and D are both correct answers
