The additive inverse property states that when you add a number and its opposite (rational numbers), the result is zero. The reason is that the inverse of a number is the opposite, so if you have a number and when do the opposite with it (add the opposite), the result will be zero. This applies to adding!!!

Write the decimal number as a fraction ( over 1 ) 1.49=1.49/1
Multiplying by 1 to eliminate 2 decimal places we multiply top and bottom by 2 10s
Numerator ( N)
N= 1.49*10*10=149
Denominator(D)
D+ 1*10*10=100
N / D =149/100
Simplifying the fraction:
149/100
149/100
1 49/100 ( Final Answer )
Answer:
w=width
l= 2w-4
perimeter of a rectangle = 34
34 = 2(2w-4+w)
34 = 4w-8+2w
34 = 6w-8
6w = 34+8
6w = 42
w = 42/6
width = 7
length = 2w-4
= 2(7)-4
= 14-4
= 10
Ack sorry the answer I put was probably wrong
