factor completely 4x5 − 20x4 − 36x3. 4(x5 − 5x4 − 9x3) x3(4x2 − 20x − 36) x2 − 5x − 9 4x3(x2 − 5x − 9)

Answers

Consider the polynomial $4x^5 - 20x^4 - 36x^3.$ It has three terms and their greatest common factor is $4x^3.$

Since

$4x^5=4x^3\cdot x^2,\n20x^4=4x^3\cdot 5x,\n36x^3=4x^3\cdot 9,$

then

$4x^5 - 20x^4 - 36x^3=4x^3(x^2-5x-9)$ (you write in brackets the same sign as the corresponding term has).

Answer: correct choice is D.

Answer: 4x^3( x^2 - 5x - 9)

Reuben is making a replica of the US flag for his school project.He uses a scale of 0.5 centimeter to 1 inch to draw the flag. The length of the scale drawing is 2.5 centimeters, and its width is 4.75 centimeters.
The perimeter of the scale drawing is 7.25 or 11.875 or 14.5 or 47.5 centimeters.
The perimeter of the actual flag is 14.5 or 29 or 47.5 or 95 inches.

Answers

Given:
U.S Flag - rectangle in shape
scale of 0.5 cm = 1 in
length of the scale 2.5 cm
width of the scale 4.75 cm

perimeter of the scale = 2(L+W) = 2(2.5+4.75) = 2(7.25) = 14.5cm

perimeter of the actual flag is:
14.5cm * 1in/0.5cm = 29 inches.

Answer:

Step-by-step explanation:

The first would be 14.5 centimeters

The second would be 29 inches
