4/10 because 4/10 plus 2/10 = 6/10 and that leaves her 4/10 of the book left hope she likes the book :D
Answer:
C
Step-by-step explanation:
No, the answer is C because when you raise a number to a negative exponent it is equivalent to one over the number to the same exponent, but positive. So, 
and not 
.
Either way you still have the exact same amount of material length no matter if melted and remolded or simply cut
1.4 negatives are opposite of positives
For this problem, the total length of fencing is equivalent to the perimeter of a rectangle. The formula for the perimeter of a rectangle is written below:
P = 2L + 2W
where L and W are the length and width dimensions
From the relationship described,
P = 350,350 ft
W = 2/3 L
Substituting this to the perimeter equation:
350,350 = 2L + 2(2/3 L)
Solving for L,
L = 105,105 ft
W = (2/3)(L) = (2/3)(105,105) = 70,070 ft
