Answer:
-x
Step-by-step explanation:
You can distribute:
(x + 3)(x – 4)
x (x + 3) – 4(x + 3)
x² + 3x – 4x – 12
x² – x – 12
Or you can use FOIL (first, outer, inner, last).
(x + 3)(x – 4)
x² – 4x + 3x – 12
x² – x – 12
Answer:
C) (6,2)
Step-by-step explanation:
Rewrite equations:
y=x−4;x+2y=10
Step: Solve y=x−4for y:
y=x−4
Step: Substitute x − 4 for y in x+2y=10:
x+2y=10
x+2(x−4)=10
3x−8=10(Simplify both sides of the equation)
3x−8+8=10+8(Add 8 to both sides)
3x=18
3x
3
=
18
3
(Divide both sides by 3)
x=6
Step: Substitute6forxiny=x−4:
y=x−4
y=6−4
y=2(Simplify both sides of the equation)
