Answer:
Solution is not correct.
Step-by-step explanation:
Given question is incomplete; Here is the complete question.
Is the solution shown in the attachment correct ?
9x + 2 = 8x² + 6x
We have to solve this equation with the help of quadratic formula,
-8x² + 9x + 2 = 6x
-8x² + 9x - 6x + 2 = 0
-8x² + 3x + 2 = 0
Quadratic formula of a standard quadratic equation (ax² + bx + c = 0) is,
x =
By comparing our equation with the standard quadratic equation,
a = -8
b = 3
c = 2
By substituting the values of a, b and c in the quadratic formula,
x =
x =
x =
Therefore, the given solution is not correct.
Answer:
A=4 I think
Step-by-step explanation:
I=a+(n-1)d
25=a+(8-1)3
25=a+21
25-21=a+21-21
4=a

Step-by-step explanation:
For this case, the first thing you should do is take into account the irrational number definition.
An irrational number is one that can not be written as the quotient between two whole numbers.
Their number of decimals is unlimited and they are not periodic.
An irrational number within the specified domain is:
π/2 = 1.570796327
Answer:
an example of an irrational number that is less than 2 and greater than 1.5 is:
π/2 = 1.570796327
