Answer:
f(-4) = 4
Step-by-step explanation:
Fro the graph attached,
We have to calculate the value of the function at x = -4.
As we can find from the graph at the input value x = -4, output value of the function is f(-4) = 4
Therefore, f(-4) = 4 will be the answer.
Answer:
Length is 182 cm and width is 158 cm.
Step-by-step explanation:
Given:
Perimeter of rectangle table = 680 cm.
Let the width of the table be .
Now according to given length of the table is 24 cm more than the race the width
hence length = .
But perimeter of rectangle = 2(length+width)
Substituting the values we get;
Hence width = 158 cm
Now, length = 24 cm + width = 24 cm + 158 cm = 182 cm
Hence the dimension of table are 182 cm and 158 cm.
