-5 x X = -5x
-4 x X = -4x
x^2 - 5x - 4x + 20
-5 - 4 = -9 so...
x^2 - 9x +20 is the answer

Answer:
V = 168 cm^3
Step-by-step explanation:
L length - 8cm
W width - 3 cm
H height - 7 cm
V = w h l (Right rectangular prism)
4x + y = 5
3x + y = 8
y = -3x + 8
4x +(-3x + 8) = 5
4x -3x + 8 = 5
x + 8 = 5
x = -3
y = -3(-3) + 8
y = -9 + 8
y = -1
Answer:
y = -2x + 7 is the equation if that's what you are asking for.
