Answer:
Option 3rd is correct.
the value of h[j(2)] is, -13
Step-by-step explanation:
Given the functions:
We have to find the value of h[j(2)]
Replace x from -2x in h(x) we have;
⇒
Substitute the value of x = 2 we get;
Therefore, the value of h[j(2)] is, -13
b. 3x - 4 = 5x - 10
c. 3x + 4 = 5x + 10
d. 3x - 4 = 5x + 10
Given:
Area of a square frame = 81 square inches.
To find:
Perimeter of the frame.
Solution:
Let length of each side of the frame = a inches.
Area of square frame is
Taking square root on both sides,
Side length cannot be negative. So, a=9 inches.
Perimeter of frame is
Therefore, the perimeter is 36 inches.
The perimeter of the frame is 36 inches.
To find the perimeter of a square, we need to know the length of its sides. Since the area of the frame is given as 81 square inches, we can find the length of one side by taking the square root of the area. The square root of 81 is 9, so each side of the frame measures 9 inches.
Since a square has four equal sides, we can find the perimeter by multiplying the length of one side by 4. Therefore, the perimeter of the frame is 9 inches x 4 = 36 inches.
