Answer:
a = 9
Step-by-step explanation:
expand (y - 3)(y² + 3y + 9)
= y³ + 3y² + 9y - 3y² - 9y - 27
compare the coefficients of like terms with
y³ + 3y² + ay - 3y² - ay - 27
ay = 9y and - ay = - 9y ⇒ a = 9
The volume of the box with a height of 10 inches and perimeter of 72 inches and width of w is 360w - 10w²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let w represent the width of the box and v represents the volume, hence:
2(w + length) = 72
Length = 36 - w
Volume = w(36 - w) * 10
Volume = 360w - 10w²
The volume of the box with a height of 10 inches and perimeter of 72 inches and width of w is 360w - 10w²
