Define x :
-----------------------------------------------
Let the width be x
Width = x
Length = 4x + 7
-----------------------------------------------
Formula :
-----------------------------------------------
Perimeter = 2 (Length + Width)
Perimeter = 74
2(4x + 7 + x) = 74 // sub length and width into the equation
2(5x + 7) = 74 // combine like terms
10x + 14 = 74 // Apply distributive property
10x = 60 // Take away 14 from both sides
x = 6 // Divide by 10 on both sides
-----------------------------------------------
Find Length and Width :
-----------------------------------------------
Width = x = 6mm
Length = 4x + 7 = 4(6) + 7 = 31mm
----------------------------------------------------------------------------------------------
Answer: The length is 31mm and its width 6mm.

Asolution of the equation ƒ(x ) = g(x ) is the same as (select all that apply)
The x-value of a solution to the system of equations y = ƒ(x ) and y = g(x ).
The x-coordinate of an intersection point of the graphs of y = ƒ(x ) and y = g(x ).
The y-coordinate of an intersection point of the graphs of y = ƒ(x ) and y = g(x ).
Answer:
$2.90
Step-by-step explanation:
Spinach $5.75
Tuna $7.20
2 lemonades $2.60
tax = $1.55
Sum = $17.10
Change = $20.00 - $17.10 = $2.90
The unit rate is 5.5
Equation: 11 divided by 2=5.5
Unit rate is how much it is for just one object
