Final answer:
To find the value of x in the given expression (3x + 20°) 400, solve for x using the coefficient of x as 3. The value of x is 400/3 or 133.33.
Step-by-step explanation:
To find the value of x in the given expression (3x + 20°) 400, we need to solve for x. The expression represents the pattern of a quilt, with horizontal lines parallel to each other.
Since all the horizontal lines are parallel, it means that the coefficient of x remains the same throughout the pattern. In this case, the coefficient is 3. Therefore, the value of x is 400/3 or 133.33.
