The given equation is
Here we have to solve for n. First we need to get rid of the denominators and for that we do cross multiplication .
Now we need to isolate n. And for that we need to get rid of 12, by dividing both sides by 12
And that's the required value of n .
1) distribute 2 to each term within the parentheses
2) combining like terms ( which means subtract a 6-2)
3) subtract 4 from both sides of the equation
4) divide both sides of the equation by 4
Final answer should be ( x = 1/4 )
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
