Option 1. and option 4. are equivalent to
Step-by-step explanation:
Step 1:
The given expression is expanded as follows.
The -2 is multiplied with the 5x and then the -2 is multiplied with the .
So the expression becomes as follows;
This is the first option given so the first expression is equivalent.
Step 2:
Of the other four options, only the fourth expression has the fraction so the fourth expression is also equivalent.
Expressions 1 and 4 are equivalent to the given expression.
100 + 50 + 3 + 7/10 + 6/100
x = 4.5 so it is 3/-8 = 4.5/12
4, 8, 12, 20
10, 20
The least common multiple of 4 and 10
I hoped this helped. :)
