Answer:
x=+5
Step-by-step explanation:
3(x+2)-2x-7=-(-5x-1)-2(x+6)
We move all terms to the left:
3(x+2)-2x-7-(-(-5x-1)-2(x+6))=0
We add all the numbers together, and all the variables
-2x+3(x+2)-(-(-5x-1)-2(x+6))-7=0
We multiply parentheses
-2x+3x-(-(-5x-1)-2(x+6))+6-7=0
We calculate terms in parentheses: -(-(-5x-1)-2(x+6)), so:
-(-5x-1)-2(x+6)
We multiply parentheses
-(-5x-1)-2x-12
We get rid of parentheses
5x-2x+1-12
We add all the numbers together, and all the variables
3x-11
Back to the equation:
-(3x-11)
We add all the numbers together, and all the variables
x-(3x-11)-1=0
We get rid of parentheses
x-3x+11-1=0
We add all the numbers together, and all the variables
-2x+10=0
We move all terms containing x to the left, all other terms to the right
-2x=-10
x=-10/-2
x=+5
Answer: The length of third side is 15.
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The perimeter of given triangle is 44.
One side, suppose a is 18.
Second side, suppose b is 11.
Suppose, third side is c.
So the perimeter will be :
Subtracting 29 in both sides
Hence the length of third side is 15. Answer
Hope it will help :)
C. 9^4
when dividing with exponents, i usually just look at the exponents and subract them so i did 12-8 for this problem
