Answer:
24 pounds
Step-by-step explanation:
Let's call the weight of the empty wheelbarrow X, and the weight of dirt to fill the wheelbarrow Y.
So, we can formulate the following equations:
X + Y = 60
X + (1/4)*Y = 33
Subtracting the second equation from the first one, we have:
3/4 * Y = 27
Y = 27 * 4 / 3 = 36
Now, we can calculate X:
X + 36 = 60
X = 24 pounds
The simplified expression of (x + y)(x - y) is x^2 - y^2
<h3>How to solve the expression?</h3>
The expression is given as:
(x + y)(x - y)
Expand the bracket
x(x - y) + y(x -y)
Further, expand
x^2 - xy + xy - y^2
Evaluate the like terms
x^2 - y^2
Hence, the simplified expression of (x + y)(x - y) is x^2 - y^2

The indefinite integral ∫dx/x is ln(x), so your integral is
... 7(ln(15)-ln(3)) = 7ln(15/3)
... = 7ln(5) ≈ 11.266065387
