Answer:
x^2 + y^2 + 2xy
Step-by-step explanation:
Use the FOIL method.
Multiply the first terms: x•x=x^2
Multiply the outer terms: x•y=xy
Multiply the inner terms: y•x=xy
(alphabetical order)
Multiply the last terms: y•y=y^2
Combine like terms:
x^2 + y^2 + xy + xy
x^2 + y^2 + 2xy
Answer:
B. -13 < x
Step-by-step explanation:
Simply evaluate to arrive at your answer.
X - shorter piece
3x - 2 - longer piece
x + 3x -2 = 18
x + 3x = 18 +2
4x = 20 | : 4
x=5
3*5 -2 = 15 - 2 = 13
shorter piece: 5 ft
longer piece : 13 ft
