Step-by-step explanation:
X^2-2=2(x^2+4x-5)-(x-4)(x-4)
X^2-2=2(x^2+4x-5)-(x^2-8x+16)
X^2-2=2x^2+8x-10-x^2+8x-16
2x^2-x^2-x^2+8x+8x-10-16+2=0
16x-24=0
16x=24
X=2
<span>6 x 298 is the same as (6 x 300) - (6 x 2)
(6 x 300) is the same as (6 x 3 x 100)
So (6 x 3) = 18
(6 x 3 x 100) = (18 x 100) = 1,800
(6 x 2) = 12
So 6 x 298 = 1,800 - 12 = 17,88</span>
I don't know what the shape is so I can't help....
As a mixed number, that would be 4 2/4, or 4 1/2 simplified.
I hope this answer helped you! Feel free to ask me any more questions if you need help! :)
F(-10) means the x value in the equation is -10.
Replace x with -10 and solve:
4(-10) -12 = -40 - 12 = -52
F(-10) = -52
