Question

Nancy is checking to determine if the expressions x+4+x and 6+2x-2 are equivalent. When x=3 , she correctly finds that both expressions have a value of 10. When x+4+x=14, she correctly evaluates the first expression to find

Answer 1

Answer:

Expressions are equivalent.

Step-by-step explanation:

Expressions are said to be equivalent if same values are obtained on plugging same number in different expressions

for example

x+4+x at x =3  gives 3+4+3 = 10

6+2x-2 at x=3 gives 6+2(3)-2 = 6+6-2 = 10

therefore given expressions are equivalent.

Answer 2
