Answer:
22.2m
Step-by-step explanation:
1 roll to 12 gifts
one gifts uses 1,85m of ribbon
1,85m is the length
12 × 1.85 = 22.2m
1.1x+1.2x-5.4=-10x
Move all terms to the left:
1.1x+1.2x-5.4-(-10x)=0
Add all the numbers together, and all the variables
2.3x-(-10x)-5.4=0
Get rid of parentheses
2.3x+10x-5.4=0
Add all the numbers together, and all the variables
12.3x-5.4=0
Move all terms containing x to the left, all other terms to the right
12.3x=5.4
x=5.4/12.3
x=3.8571428571429/8.7857142857143

Answer:
Given sides of triangle
a=13,b=14,c=15
Semi-perimeter s=
2
1
(a+b+c)=
2
1
(13+14+15)=21
Area, A =
s(s−a)(s−b)(s−c)
A=
21(21−13)(21−14)(21−15)
103 cm 115 cm 13 cm are same way
