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

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.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
