A regular triangle is a triangle with 3 equal sides. A perimeter of a triangle with 3 sides = 3 x length = 3 (length). Since you know that the perimeter is also equal to 18x + 27, therefore,
3 (length) = 18 x + 27
length = (18x + 27) / 3 <-- divided both sides by 3
length = 6x + 9
An expression for the length of one of its sides is 6x + 9.

Answer:

Step-by-step explanation:
Given


Required
Model the situation using an equation
Represent the number of orders with n
Represent the balance with y
y is calculated as:

We used minus because the amount is being deducted


Well to find volume you just have to multiply all 3 lengths so... 19*23*8=A)3496 in^3
