Let's call the length of the rectangular fence 
and the width of the rectangular fence 
.
Based on the information in the problem, we can make two equations, based on the formulas for perimeter and area:
Now, let's substitute in the values we are given in the problem:
Now, let's solve the system using substitution.
- Solve for from the first equation
- Substitute this value into the second equation
- Multiply both sides of the equation by
- Subtract
from both sides of the equation
and 
- Use the Zero Product Property and solve both factors
We are given two possible lengths. However, the funny thing is that both produce the same dimensions: 24 ft by 10 ft:
Thus, our answer is Choice C, or 10 feet by 24 feet.
1) B. C1=90
2) B. C2=50+0.20m
3) B. C1=90
4) B. C2=50+0.20*300=$110
5) The Vodaphone plan works best for Kira since it is $20 cheaper.
6) Yes, 200 minutes of calling time.
Answer:
8/15
Step-by-step explanation:
basically when dividing fractions, flip the second number upside down and divide. so basically you multiply 2/9 times 12/5, which is 24/45. simplify by dividing by 24/45 by 3, which is 8/15
Answer:
T(c) = 100 + 3*c
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
T(c) = 100 + 3*c
B = 44+A
AB = A(44+A) = 44A + A^2
d(AB)/dA = 44+2A = 0
A = -44/2 = -22
B = 44-22 = 22
