Answer:
The negative solution is -1
Explanation:
Let the number is x.
According to the question:
4 times of x will be 4x
- 5 less of the square of that number will be x² -5
Therefore,
4x = x² – 5
Make this equation in the form of a quadratic equation
x² - 4x -5 = 0
(x - 5) (x + 1) = 0,
The value of x = 5, and x = -1
The negative value of x of two solutions is -1.
Answer and Explanation:
Function of the skeletal muscle:
Skeletal muscles move the body. Its compression pull on ligaments, which are appended to bones. In the event that withdrawal of the muscle makes the muscle abbreviate, the bone and, in this way, the movement of the body part occurs.
Structure of the skeletal muscle:
It's appended deep down and shapes a particular organ of muscle tissue, veins, ligaments, and nerves that covers our bones and permits movement. Skeletal muscles frequently exist two by two, whereby one muscle is the essential mover and different goes about as an antagonist.
