Answer:
3x^2−4x−4
Step-by-step explanation:
3x^2−8x−2+4x−2
=3x^2+−8x+−2+4x+−2
3x^2+−8x+−2+4x+−2
=(3x^2)+(−8x+4x)+(−2+−2)
=3x^2+−4x+−4
Answer:
x=1/2 or 0.5
B. 0.5
Step-by-step explanation:
Step one: Add x to both sides
you then get the equation 7=4x+5
Step two: subtract 5 from both sides
you then get the equation 2=4x
Divide both sides by 4 to undo the multiplication.
2/4=4x/4x
you get x=2/4 which simplifies to 1/2.
