Let length of base be x and breadth of base be y

2x + 2y = 28
x + y = 14
y = 14 - x

Volume of box
= 5xy
= 5x (14 - x)
= 70x - 5x^2

Write the equation of a line that is perpendicular to the given line and that passes through the given point.
HACTEHA [7]
First, let's re-arrange to slope-intercept form.

x + 8y = 27

Subtract 'x' to both sides:

8y = -x + 27

Divide 8 to both sides:

y = -1/8x + 3.375

So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.

So the slope of the perpendicular line will be 8.

Now we can plug this into point-slope form along with the point given.

y - y1 = m(x - x1)

y - 5 = 8(x + 5)

y - 5 = 8x + 40

y = 8x + 45

Is the figure an example of a segment?
Radda [10]

Answer: yes, it extends infinitely in opposite directions

Step-by-step explanation:

Examples of line segments include the sides of a triangle or square. More generally, when both of the segment's end points are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if they are adjacent vertices, or otherwise a diagonal.

Geometry help! Find part B
hram777 [196]

Answer: It looks like Part B is about 4 times that of part A.

Step-by-step explanation: I think the answer would be 12.

A would be 3. B would be 12.

I'm terribly sorry if it is wrong.
