Answer:
The options 2x² + x² + x = 30 and 9x + 3x² = 14 + x + 1, and -x² + 4x + 7 = - x² - 9
Step-by-step explanation:
After being rearranged and simplified, which of the following equations could be solved using the quadratic formula?
The answers are:
2x² + x² + x = 30
9x + 3x² = 14 + x + 1
-x² + 4x + 7 = - x² - 9
all that he checked except for D
D is Incorrect. A and C are Correct
The value of x is staring at you in the given hypotenuse.
Each leg = x
Hypotenuse = x•sqrt{2} = 100•sqrt{2}
So, x = 100
M- 300
N- 225
525 - 75 = 450
450/2= 225
225 + 75 = 300
A (g(x) = }(x-2)5.1).
5x=30
