Select the correct answer from each drop-down menu.
a rope is cut into three pieces. the lengths are given as 2ab(a − b), 3a2(a + 2b), and b2(2a − b).
the expression representing the total length of the rope is .
if a = 2 inches and b = 3 inches, the total length of the rope is inches.
math

1)

2) 93 inches

Step-by-step explanation:

1) We know that the lenghts are given by these expressions:

Then, we need to add them in order to find the expression that represents the total length of the rope:

- Apply Distributive property.

- Add the like terms.

Then:

2) Knowing that:

We must substitute these values into in order to caculate the total lenght of the rope. This is:

slope is 35 and 20 miles is the y-intercept.
