the lengths of the sides of a triangle are in the ratio 5:6:7. describe the length of the longest side if the perimeter is less
2 answers:
Answer:
Less than 21 cm.
Step-by-step explanation:
Let x represent the multiplier.
We have been given that the lengths of the sides of a triangle are in the ratio 5:6:7. The perimeter of all sides of the triangle would be .
We have been given that the perimeter is less than 54 cm.
We can set this information in an inequality as:
Since the length of longest side is , so:
Therefore, the length of the longest side will be less than 21 cm.

Answer:
Option D
Step-by-step explanation:
We have to find the value of the composite function (h o k)(2).
Since, (h o k)(x) = h[k(x)]
(h o k)(2) = h[k(2)]
From the picture attached,
At x = 2
k(2) = (-2)
Therefore, h[k(2)] = h(-2)
Since, h(x) =
Therefore, h(-2) =
= -3
(h o k)(2) = -3 is the answer.
Option (D) is the correct option.
