Step-by-step explanation:

Equivalent expressions are those expressions that have the same value but they look different.

Given the following expression provided in the exercise:

You need to remember the multiplication of signs in order to find the equivalent expressions:

Then:

- Eliminating the parentheses, you get this equivalent expression:

- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:

This is an equivalent expression to

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
