Which polynomial is factored completely? a) g^5 - g
b) 4g^3 + 18g^2 + 20g
c) 24g^2 - 6g^4
d) 2g^2 + 5g + 4
Answers
This is because the terms in the polynomial do not have any common factors.
a) g⁵ - g can be factored into g(g⁴ - 1)
b) 4g³ + 18g² + 20g can be factored into 2g(2g² + 9g + 10)
c) 24g² - 6g⁴ cab be factored into 6g²(4-g²)

Answer:
Mass of A = 5760 grams
Step-by-step explanation:
Surface area is given, so we can set-up a similarity equation to solve for k, proportionality constant. Here, we will relate both of them through k^2, because they are 2 dimensional (area). Thus
Surface Area of A = k^2 * Surface Area of B
28 = k^2 * 40.32
k^2 = 28/40.32
k^2 = 25/36
k = Sqrt (25/36)
k = 5/6
Now, we want to find mass (1 dimensional quantity), thus we can say:
Mass of A = k * Mass of B
Mass of A = (5/6) * (6912)
Mass of A = 5760 grams
Answer:
The mass of A is 4000g.
Step-by-step explanation:
First, divide 28 by 40. Then square root this to get the scale factor between them. (5 over 6). Mass is like volume in this case, so we need to cube 5/6 and then multiply that by 6912 to get the mass of A.
28÷40.32= 25/36
√25/36 =5/6
5/6³ x 6912= 4000g

The length of the edge of the given cube that has a lateral area of 36 square inches is: 3 inches.
What is the Lateral Area of a Cube?
Lateral area of a cube = 4a², wherea is the length of each edge of the cube.
Given the parameters:
- Lateral area = 36 square inches
- Length of each edge = a = ?
4a² = 36
a² = 36/4
a² = 9
a = 3 inches.
Length of each edge of the cube = 3 inches.
