Answer:
look at the equation carefully and solve it .
Step-by-step explanation:
Answer:
All of the rugs are the same size after making the cuts. The vertical line goes down the center of the rectangle, making two congruent parts. The diagonal line also splits the rectangle into two congruent parts because the area of a right triangle is exactly half the area of the rectangle.

D) six and two sixths minus three and two eighths
Answer:
14 days
Step-by-step explanation:
1. Convert the amount of work person A and B can do respectively in one day into fractions.
A = 1/16 B = 1/12
2. Get both fractions to a common denominator using the least common multiple. This is 48.
1/16 × 3 = 3/48 1/12 × 4 = 4/48
3. Add both fractions to find out how much work will be done in two days. We are doing this because we are working in a pattern, and this will allow us to multiply, which is more time efficient than repeatedly adding 3 and then 4.
3/48 + 4/48 = 7/48
4. Figure out how many sets of two days work (7/48) will get them to 48/48 (100% done) or closest to it without being under. This would be 7 sets.
7/48 × 7 = 49/48
5. Multiply 7 by 2. We are doing this because we worked in sets of two days to account for A working and then B, since they are taking turns.
7 × 2 = 14
6. It will take them 14 days.
Answer:
c a(n+10)
Step-by-step explanation:
[(-1)^(n+1)] × (5^n)
an > 0
a(n+5) = (-1)⁵ × 5^(n+5) < 0
a(n+10) = (-1)¹⁰ × 5^(n+10) > 0
a(n+15) = (-1)¹⁵ × 5^(n+15) < 0
Since a^n is positive, n is even
Odd powers of -1 are negative
