The value of x is equal to 1.5.
It is required to find x.
<h3>What is quadratic equation?</h3>
Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.
Given that:
So for the triangle, the perimeter would be:
By solving in above equation, we get
So, we take x= 1.5 and neglect -4 because we can't take negative roots of the quadratic equation.
Hence, the value of x is equal to 1.5.

Answer:
60
Step-by-step explanation:
80/100 times 75 and you will get 60
(1.6 * 10^3) * (3.0 * 10^-6) =
(1.6 * 3.0) * (10^3 * 10^-6)
4.8 * 10^(3 - 6) =
4.8 * 10^-3 =
4.8 * 1/10^3 =
4.8 / 10^3 =
4.8 / 1000 =
0.0048 <==
This is the concept of arithmetic. To calculate the percentage of time life has existed we proceed as follows;
According to history:
The age of earth is 4.6 billion years
the age of life is as it appeared from unicellular is 3.8 billion years.
thus the percentage of the above will be:
3.8/4.6 x 100
=0.82609x100
=82.609%
Answer: Percentage of female workers = 40%
Step-by-step explanation: No of Female workers = 80
No of Male workers = 120
