Answer:
-150 (x^2y+2)y³
Step-by-step explanation:
To Find the product of 25x^2y and -6x²y3.
(25x^2y) (-6x²y³)
= 25(-6) (x^2y+2) y³
= -150 (x^2y+2)y³
10+ ?= 49
⇒ ?= 49-10
⇒ ?= 39
10 plus 39 can give you 49~
A= 30
Explanation: 88-58=30
Take 4,000 times 12 to get 48,000. that’s how much A costs.
B is a little harder. you have to take (2,300+300)x12+(4*250). this equals $32,100
the correct answer would be B.
