Jeffrey has an aquarium in the shape of a rectangular prism. He is going to place a layer of sand over the base for his iguana.

nikitadnepr [17]

Answer:

$Length = 6x^2 - 2x + 3$

Step-by-step explanation:

Given

$Area = 42x^3 - 14x^2 + 21x$

$Width = 7x$

Required

Determine the length of the aquarium

The area of a rectangular base is calculated as:

$Area = Length * Width$

Substitute values for Area and Width

$42x^3 - 14x^2 + 21x = Length * 7x$

Make Length the subject

$Length = \frac{42x^3 - 14x^2 + 21x}{7x}$

Factorize the numerator

$Length = \frac{7x(6x^2 - 2x + 3)}{7x}$

$Length = 6x^2 - 2x + 3$

Answer:

Choice 1

Step-by-step explanation:

Let‘s go through each answer and analyze a

each.

Choice 1

Parallel means to lines with the same slope, they never intersect, ever, they always remain next to each other and never touch. This is true for the picture

Choice 2

Perpendicular means that two lines intersect at a right angle, however upon looking at the picture you can see this is not a right angle, but an acute angle. So it is not perpendicular.

Choice 3

A Line Segment means a line with dots on either end, symbolizing the end of the line. This is not a line segment because there are arrows on the ends, indicating these lines go on forever. This is not a segment

Choice 4

We already determined this is neither a segment nor perpendicular so it cannot be this choice

This leaves us with Choice 1.

I hope this helps!

Please give thanks and brainliest!
