Answer:
.....................
10)=(-3)^2.x^4×2.y^2(5.x^2y^6)-7^2x^5×2y^4×2
=(9×5)x^8+2y^2+6-49x^10y^8
=45x^8+2y^2+6-49x^10y^8
=45x^10y^8-49x^10y^8
=-4x^10y^8
bni already took this it was correct
Step-by-step explanation:
jst
I think it would take 6 minutes to reach temperature below 8 °C
Its infinite solutions because its the same exact thing when you simplify the first half of the problem.
