Yea! Brainliest :-)
The answer is 3 because the length of the box is 10, the width is 5, and the height is 3.
Answer:
1 Rearrange the equation so "y" is on the left and everything else on the right.
2 Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
3 Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
Step-by-step explanation:
Answer:
Step-by-step explanation:
Expression for the rectangular area and perimeter are, respectively:
After some algebraic manipulation, area expression can be reduce to an one-variable form:
The first derivative of the previous equation is:
Let the expression be equalized to zero:
The second derivative is:
According to the Second Derivative Test, the critical value found in previous steps is a maximum. Then:
The maximum area is:
X intercepts: (-8, 0)
Y intercepts: (0, 4)
