I want to say D but i am not for sure look up examples and see which one comes to mind
I assume the way it's written is like this
4x^2 - 8x + 4 - (2x^2 - 3x + 7)
If that's the case, just combine like terms.
Let's begin with 4x^2. It has the same components as the -2x^2 (remember, since it's being subtracted in the original equation, the number is negative.)
4x^2 - 2x^2 = 2x^2
Now -8x and 3x (be careful, sometimes there's a minus sign in and out of the parentheses, this makes the number positive again
-8x + 3x = -5x
And then 4 and -7
4 - 7 = -3
So the simplified version is finally:
2x^2 - 5x - 3
Hope this helped! If you need me to explain anything, don't be afraid to ask.
Answer:
(-2)^4 = (-2) * (-2) * (-2) * (-2) = 16

(-7)² = (-7) * (-7) = 49
Answer:
Step-by-step explanation:
Hello : let A(-7,3) B(-6,-1)
the slope is : (YB - YA)/(XB -XA)
(-1-3)/(-6+7) = -4/1 =-4
an equation is : y=ax+b a is a slope
y = -4x +b
the line through point B (-6,-1) : -1 = (-4)(-6)+b
b = -25
the equation is : y =-4x-25
2x-4
If x is the amount the other team scored then the 2x is double. This gives that 4 less than double the amount of the other team would be minus 4
