It depends, what does a mean? If you know just add what a means to 3 then subtract 4.
Answer:
Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.
Step-by-step explanation:
It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.
We have to find the expression which represents the perimeter, in centimeters, of the triangle.
Perimeter of a triangle = Sum of its all the sides.

On combining like terms, we get



Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.
They are made by 1. 4 is made by 2, 8 is made by 2 and 4, 6 is made by 2 and 3.
The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
<h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the total cost of hiring for x hours. Hence:
- Using the points (0, 125) and (15, 950)

The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
