Answer:
A. (x−2y)(y−3x)
=(x+−2y)(y+−3x)
=(x)(y)+(x)(−3x)+(−2y)(y)+(−2y)(−3x)
=xy−3x2−2y2+6xy
=−3x2+7xy−2y2
B. (2p+3)(p2−4p−7)
=(2p+3)(p2+−4p+−7)
=(2p)(p2)+(2p)(−4p)+(2p)(−7)+(3)(p2)+(3)(−4p)+(3)(−7)
=2p3−8p2−14p+3p2−12p−21
=2p3−5p2−26p−21

Answer:
Agree.
Step-by-step explanation:
1. (5^r)^t can be represented simply as 5^rt.
2. when r as negative integer, t as positive integer, rt is always a negative integer
3. when ever the indices rt is negative, the number 5^rt will be less than 1, thus cannot be a whole number for sure.
Answer:
m=9n
Step-by-step explanation:
Linear equation, straight forward m=3n. Highlighted point is n=3 and m=9*3=27
The equation is y=(-1/2)x +2
