3. Use the polynomial 12x^4 y^2 + 30x^3 y to answer the following questions?

barxatty [35]

Answer:

$\huge\boxed{GCF:6x^3y}$

$\huge\boxed{Factored: 6x^3y(2x+5)}$

Step-by-step explanation:

Look at both terms separately, and isolate each "part."

i.e. 12x^4y^2 becomes 12, x^4, y^2

So the problem becomes:

12, x^4, y^2 and

30, x^3, y^1

Then, find the GCF of each term,

30 and 12 - 6

x^4 and x^3 - x^3

y^2 and y^1 - y^1

Hope it helps :) and let me know if you want me to elaborate.

Use a table to multiply (x – 1)(3x + 2)

Naily [24]

Hello,

The answer is <u>3x² - x - 2</u>

<h3>Step-by-step explanation:-</h3>

<u>Step 1</u> : Apply distributive property by multiplying each term of " x - 1 " by each term of 3x + 2 :-

→ 3x² + 2x - 3x - 2

<u>Step 2</u> : Combine 2x and -3x to get -x :-

→ <u>3x² - x - 2</u>

The volume of a rectangular prism is a minimum of 25 cubic feet. The height of the prism is 3 feet more than its width, and its

ella [17]

Answer: Option C, she used the wrong symbol in the first inequality.

Step-by-step explanation:

For a rectangular prism of length L, width W and height H, the volume is:

V = L*W*H

We know that the volume of the prism is a minimum of 25 ft^3

Then:

V ≥ 25ft^3

We also know that:

"The height of the prism is 3 feet more than its width"

H = W + 3ft

"and its length is at most 5 feet more than the width"

L ≤ W + 5ft

Then we have the system:

V ≥ 25ft^3

H = W + 3ft

L ≤ W + 5ft

Now we can rewrite the volume as:

V = L*W*H

V = L*W*(W + 3ft)

Now we can replace L by the inequality L ≤ W + 5ft

Then we get:

V ≤ (W + 5ft)*W*(W + 3ft)

V ≤ W^3 + 8ft*W^2 + 15ft*W

Then the inequalities are:

V ≤ W^3 + 8ft*W^2 + 15ft*W

V ≥ 25ft^3

Then the error in Carla's system is the symbol of the first inequality, where Carla used "<" instead of "≤"

The correct option is C
