Answer: a. 1 feet by 13 feet
Step-by-step explanation:
Let L represent the length of the rectangular vegetable garden.
Let W represent the width of the rectangular vegetable garden.
She wants to have a total area of 13 square feet. This means that
LW = 13 - - - - - - - - - - -1
The garden should be 12 feet longer than it is wide. This means that
L = W + 12
Substituting L = W + 12 into equation 1, it becomes
W(W + 12) = 13
W² + 12W = 13
W² + 12W - 13 = 0
W² + 13W - W - 13 = 0
W(W + 13) - 1(W + 13)
W - 1 = 0 or W + 13 = 0
W = 1 or W = - 13
Since the width cannot be negative, then W = 1 feet
L = W + 12 = 1 + 12
L = 13 feet
Answer:
Step-by-step explanation: for 2 hours there is 120 divide that by 5 and u get 24, now divide 24 by 2 and u get 12. So there are 12 commercials during that 2 hour football game
The domain is going to be all ur x values...so the domain is { -4,-1,1,4 }....the range will be all ur y values...so the range is { -1,1,4} ...the reason there is only 3 numbers is because if the numbers repeat, u only have to write them once.
A function will not have any repeating x values....they can have repeating y values, just not the x ones. So if all ur x values are different, then it is a function. Therefore, this is a function.
