x + 2x + 3 = 30

Respuesta :

Answer:

A: 3x+2=30

Step-by-step explanation:

An equation is formed of two equal expressions. The correct option is B.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the length of Zach's cars be represented by x.

Given that Ginny's car is 2 more than 3 times the length of Zach's car. Therefore, an expression can be written as,

Ginny's car length = 3x + 2

Also, the sum of the lengths of both cars is 30 inches. Therefore, the length of the two cars is,

x + 3x + 2 = 30

Hence, the correct option is B.
