Answer:
C. -13x0
Step-by-step explanation:
-13x0 will not give you a negative or positive number. This is because any number time 0 gives you 0, and zero is the only number that is neither positive nor negative. Every other expression will give you a nonzero number, which must be positive or negative.
One side of the back yard is usually the back side of the house.
But we won't worry about that ... we'll just go ahead and fence all
four sides, like you seem to have said.
Any rectangle has two sides that are the length and two sides that are the width.
So the distance around the back yard is
(14 + 14) + (12 + 12) = 52 meters.
(That's called the "perimeter" of the yard.)
If every meter of fence costs $9.00 , then 52 meters of fence will cost
(52) times ($9.00) = $468 . plus tax.
Answer:
Step-by-step explanation:
32a²b² = 2 * 2*2*2*2 * a² * b²
36a²c² = 2 * 2 * 3 * 3 * a² * c²
16ab³ = 2 * 2 * 2* 2 * a * b³
Greatest common factor = 2*2*a = 4a
32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)
