The solution to the binomial expression by using Pascal's triangle is:



<h3>How can we use Pascal's triangle to expand a binomial expression?</h3>
Pascal's triangle can be used to calculate the coefficients of the expansion of (a+b)ⁿ by taking the exponent (n) and adding the value of 1 to it. The coefficients will correspond with the line (n+1) of the triangle.
We can have the Pascal tree triangle expressed as follows:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1

From the given information:
The expansion of (3x-4y)^11 will correspond to line 11.
Using the general formula for the Pascal triangle:

The solution to the expansion of the binomial (3x-4y)^11 can be computed as:

Hello There!
We know that the painter had the steamer from 9 a.m in the morning to 4 p.m in the afternoon
he had it for a total of 7 hours. 28.84 divided by 7 equals 4.12 an hour
Divide $28.84 by 7 hours.
28.84/7 = 4.12
The rental cost per hour was $4.12.
