2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.
If you would like to know what percent is 27.30 of 36.40, you can calculate this using the following steps:
x% of 36.40 = 27.30
x/100 * 36.40 = 27.30
x/100 = 27.30/36.40
x = 27.30/36.40 * 100
x = 75
To check: 75% * 36.40 = 75/100 * 36.40 = 27.30
The correct result is 75%.
The answer is the first two inequalities ........
