(ab+3)(ab−3)
=(ab+3)(ab+−3)
=(ab)(ab)+(ab)(−3)+(3)(ab)+(3)(−3)
=a^2b^2−3ab+3ab−9
=a^2b^2−9
Answer:

Answer:
x+1 meters
Step-by-step explanation:
Area = Length * Width
x^2 - 6x - 7 = length * (x-7)
x^2 + x - 7x - 7 = length * ( x-7)
x*(x+1) - 7*(x+1) = length * (x-7)
(x-7)*(x+1) = length * (x-7)
x+1 = length [for (x-7) not equal 0]
