<span>1. </span><span>So in every 1 hour, there’s 281
gallons go through in a certain valve.
Now, let’s find the total number of gallons that will go through in 91 hours.
Let’s assign a variable for the value of total number of gallons.
Let x be the value of number of gallons
x = number of gallons in 91 hours
=> 281 gallons/ hr
=> 281 x 91
=> 25 571 gallons / 91 hours
Thus, x = 25 571 gallons will go through the open valve in 91 hours,

The area of the L shaped figure is 258 ft²
<h3>
Area</h3>
Area is the amount of space occupied by a two dimensional figure.
The area of a rectangle is given by:
Area = length * breadth
From the diagram, the area is:
Area = [18 * (21 - 12)] + (12 * 8) = 258 ft²
The area of the L shaped figure is 258 ft²

The answer is (1) x=-2. The property of the equation like y=ax2+bx+c is that the axis of symmetry of the graph is x=-b/2a. So for this question, the axis is x=-4/2=-2.
Answer: The coefficients of binomial expansions are calculated using Pascal's triangle.
