Solve for x over the real numbers:2 x^2 - 3 x - 2 = x + 4
Subtract x + 4 from both sides:2 x^2 - 4 x - 6 = 0
The left hand side factors into a product with three terms:2 (x - 3) (x + 1) = 0
Divide both sides by 2:(x - 3) (x + 1) = 0
Split into two equations:x - 3 = 0 or x + 1 = 0
Add 3 to both sides:x = 3 or x + 1 = 0
Subtract 1 from both sides:Answer: x = 3 or x = -1
403.2 cubed inches because 3 times 4 times 3.14 is 403.15 which rounds to 403.2
That would be (171 + x) / 2....what u do to find the average is add up all the numbers, then divide by how many numbers there are.
I don’t know the answer sorry
