Solution
To find out which expressions represent the difference of exactly
two expressions
a) 6(x+7) - 2
This can be simplified as
6x + 42 - 2
6x + 40
Clearly this does not represent difference of the two
expressions .
b) -2j
Clearly this represents a single expression , this does not represent
a difference of 2 expression .
c) 4f - 2g
Here we have 2 different expressions 4f and 2g
Difference of these 2 expressions are 4f - 2g
Hence , this option represent difference of exactly two
expression
d) 3xyz - 10
3xtz - 10 represnts a single expression
Here we have a single expression
Therefore it does not represent difference of exactly 2
expression .
Answer:
3100ft
Step-by-step explanation:
There are 2 sides to the prism that have an area of 50ft * 10ft or 500ft. The total of those will be 500ft * 2 or 1000ft. There are 2 more sides to the prism that have an area of 30ft * 10ft or 300ft. The total would be 300ft * 2 or 600ft. Then the last two sides to the prism have an area of 50ft * 30ft or 1500ft. Since we're imagining this prism to be a house, you can't paint the floor (well, I guess you could but I think they want us to leave that part out because you can't pick the house up to paint the bottom that would be ridiculous). So the surface area is each area added, or 1000ft + 600ft + 1500ft = 3100ft.
