Answer:
Step-by-step explanation:
move all the terms to the right so your equation will equal 0. then look for the common denominator. which in this case is 60 (5*4*3).
multiply all terms by 60 then simplify.
12(2x-3)-15(6-3x)+120-20(7x)=0
24x-36-90+45x+120-140x=0
combine like terms and then divide
-71x=6
x=-6/71
(do not forget parenthesis when simplifying they are very important when it comes to distributing the minus sign)
7.9
Step-by-step explanation:
Answer:
its 37 lol
Step-by-step explanation:
5.7 is the answer because if one side is 7.9 the parallel is the same a rectangle. The is you add those, you get 15.8. The equation now is 15.8+x=27.2. 27.2-15.8 is 11.4 which is then divided to find the two sides which makes them 5.7.
It is a scalene triangle.
