Which expressions are equivalent to x+2y+x+2

Step-by-step explanation:

To get equivalent expression we simplify the expression by combining the like terms

the terms that has same variables are like terms

x  and x  are like terms

x  or 1x  are same

2y and 2  are not like terms. So it remains the same

Equivalent expression is

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
