The correct answer would be 4x(2x+3)
7(3-x)+1 .. first you're going to distribute
21-7x+1 .. then combine like terms
22-7x .. subtract 22 from both sides to get the variable X alone.
-7x=-22
x=3.14
Answer:

Step-by-step explanation:
We would multiply the fraction by its conjugate
( A conjugate is a expression that has the same integer or number values but have different signs) for example

and

ARE Conjugates.
The conjugate of

is

So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.
Our new numerator will be

We can apply the difference of squares for the denominator.

So our denominator will be

So our rationalized fraction will be

Answer:
x ≤8/5
Step-by-step explanation:
6x - 9 ≥ 11x - 17
Subtract 6x from each side
6x -6x-9 ≥ 11x - 17-6x
-9 ≥ 5x- 17
Add 17 to each side
-9+17≥ 5x - 17+17
8≥ 5x
Divide each side by 5
8/5≥ 5x /5
8/5≥ x
