The width of the rectangle as a function of its length is w = 55/l
<h3>How to find the area of a rectangle?</h3>
The formula for finding the area of a rectangle is expressed as:
A = lw
where
l is the length
w is the width of the rectangle
Given that A = 55 square inches, then;
55 = lw
w = 55/l
Hence the width of the rectangle as a function of its length is w = 55/l

Answer:
The mother is 30 and the daughter is 6
Step-by-step explanation:
When solving for this, you can derive the equations
x=5y and x+6= 3(y+6)
x= mother and y= Daughter
Solve the equations by substituting the first equation into the places of x in the second equation to get the value of x. Next, pug in the value of x and solve for y.
