The prove to show that the area of the shaded portion is 18x - 30 is as follows: 3x² + 13x - 30 - 3x² + 5x = 18x - 30
<h3>How to find the area of the shaded region?</h3>
The area of the shaded region can be represented as follows:
area of the shaded region = area of rectangle - area of triangle
Therefore,
area of the rectangle = (x + 6)(3x - 5)
area of the rectangle = 3x² - 5x + 18x - 30
area of the rectangle = 3x² + 13x - 30
area of triangle = 1 / 2 × 2x × 3x - 5
area of triangle = 3x² - 5x
Therefore,
area of the shaded portion = 3x² + 13x - 30 - 3x² + 5x
area of the shaded portion = 18x - 30

Answer:
-3n + 18
Step-by-step explanation:
an = dn + (a - d)
The difference is -3.
The first term is 15.
an = -3n + (15- (-3))
an = -3n + 15 + 3
an = -3n + 18
Yes!
This would be in-fact a linear equation!
<h3>How?</h3>
This equation is set up in y=mx+b form, therefore we know it is a linear equation.
<h3>Example of a linear equation:</h3>
y=12x+2
The 12 is the mx in the equation.
And the 2 is the B in the equation! :)
That is how we solve that.
Any questions?
Have a great day!
Answer:
The value of the total ticket sales is, 2500
Step-by-step explanation:
Let x be the total ticket sales.
As per the statement:
if 15% of the total ticket sales is $375
then;
Divide both sides by 15 we have;
multiply both sides by 100 we have;
x = 2500
Therefore, the value of the total ticket sales is, 2500
