Help me please it just hard for a newbie like me
Makovka662 [10]
Hello there,
Part 1:
Perimeter of Red = 11+11+11+11 
                            = 44
Perimeter of Blue= 6+6+6+6
                            = 24
Ratio: Red : Blue
             44 : 24(divide by 4) 
              11 : 6
Part 2:
Area of Red= 11 x 11
                   = 121
Area of Blue= 6 x 6
                   = 36
Ratio: Red : Blue
             121: 36
             
Hope this helps :))

Multiply all terms by 15
3x+3x= 10x+30

Combine like terms
6x=10x+30

Subtract 10x from both sides
-4x=30

Divide both sides by -4
x= -7.5

Final answer: -7.5
