Answer:
No.
Step-by-step explanation:
The definition of a function is that every output (x) has only one input (y).
Here -3 gives two different outputs which contradicts the definition of a function.
Step-by-step explanation:
all I know is the answer and it's c
They look like ovals, hmm looks to be the answer is oval.
Let one side be x and the other be y
Perimeter is 68 meters
2(x + y) = 68
x + y = 34
x = 34 - y ------------------ (1)
Area = 280
xy = 280 ------------------- (2)
Sub (1) into (2):
(34 - y)y = 280
34y - y² = 280
y² - 34y + 280 = 0
(x - 14)(x - 20) = 0
x = 14 or x = 20
The dimension of this rectangle is 14 meters by 20 meters
because anything that you multiply or divide by zero would always equal zero. It's sort of just a rule of thumb
