First you must distribute the 2x to the numbers inside the parentheses
(2x * x) + (2x * -1) = 3
- 2x = 3
To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides
- 2x - 3 = 0
Use the quadratic equation to solve this (image of the quadratic equation is below)
Remember that quadratic functions are set up like so:
That means that in this equation...
a = 2
b = -2
c = -3
^^^Plug these numbers into the quadratic equation and solve...
Keep in mind that +/- is ±

Answer:
Step-by-step explanation:
1 edge: 30in
top + 4 sides: 150in to be covered by tile
1 tile: 3in
How many tiles will Raj need to cover 150 inches?
3in x 50 = 150in
Therefore, Raj will need 50 ceramic tiles to cover the top and four sides of the table.
Answer:
50 tiles
(please tell me if I am wrong, but hope I helped)
(180 miles=7.5 hours, 20 miles=2.5/3=0.8333) 7.5+0.8333=8.3333 or 8h and 20 minutes.
Given the equation 4(3b + 2)² = 64,
dividing both sides of the equation by 4, we have
(3b + 2)² = 16 and getting the square root of both sides,
(3b + 2) = 4 and (3b + 2) = -4
We can solve for b for each equation and have
3b = 2 | 3b = -6
b = 2/3 | b = -2
Therefore, the values of b are 2/3 and -2 and from the choices, the answer is <span>A: b = 2/3 and b = -2.</span>
Answer:
For the length I think you meant 32, and if you did it is $14.40
If not and you meant length of 2 it is $0.90
