Of the four expressions presented here, which two are equivalent? expression i: 6n + 5 expression ii: 2n + 5 + n + 3n expression iii: 5n + 5 expression iv: 11n

Option i and ii are equivalent.                                          

Step-by-step explanation:

Given :

Expression i - 6n+5

Expression ii - 2n + 5 + n + 3n

Expression iii - 5n + 5

Expression iv - 11n

To find : Of the four expressions presented here, which two are equivalent?

Solution :

We seen that expression i , ii, ii are nowhere equivalent to each other.

So, we solve expression ii and check

Expression ii - 2n + 5 + n + 3n = 6n+5

So, Expression ii is equivalent to expression i.

Therefore, Option i and ii are equivalent.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
