Which is the best description of the equivalency of the two expressions? Expression 1
5x? - 2x-4+6x+ 3
Expression 2
6x² - 6x+6-x?+ 10X-7
The two expressions are not equivalent because when X= 2, the two expressions do not have the same value.
The two expressions are not equivalent because when they are simplified, they do not have the same coefficients
for the x? and x terms.
They are equivalent because the sum of the constants is the same in both expressions.
They are equivalent because when x = 2, the two expressions have the same value

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
