10 billion years.
Answer:
-5x² +6x
Explanation:
The given expression is :
-3x(x-4)-2x(x+3)
It can be done as follows :
-3x(x-4)-2x(x+3) = (-3x)(x)-(-3x)(4) - 2x(x)-2x(3)
= -3x² +12x -2x² -6x
= -3x²-2x² +12x-6x
= -5x² +6x
Hence, the equivalent expression is equal to -5x² +6x.
Also known as global warming, it refers to the rise in average surface temperatures on Earth. This is mainly cause of fossil fuels which release carbon dioxide and other green house gasses into the air.
