Answer:
2n(n + 5)(n + 6)
Step-by-step explanation:
given the expression
2n³ + 22n² + 60n ← factor out the common factor of 2n from each term
= 2n(n² + 11n + 30) ← factorise the quadratic
consider the factors of the constant term (+ 30) which sum to give the coefficient of the n- term (+ 11)
the factors are + 5 and + 6 , since
+ 5 × + 6 = + 30 and 5 + 6 = + 11
use these factors to split the n- term
n² + 5n + 6n + 30 ( factor the first/second and third/fourth terms )
= n(n + 5) + 6(n + 5) ← factor out (n + 5) from each term
= (n + 5)(n + 6)
Then
2n³ + 22n² + 60n
= 2n(n + 5)(n + 6) ← in factored form
One more than a number is at least seven. x + 1 > 7
The maximum value of a number is 29. x < 29
The difference of a number and ten is at least 91. x - 10 > 91
Answer:
Step-by-step explanation:
Let the unknown number be x
Three is less than a number: for less than we use < symbol
3 < a number becomes
One more than a number is at least seven: Number atleast 7 means 7 or more than 7. So we use ≥ 7. One more than a number is x+1
The maximum value of a number is 29: maximum value of x is 29 , so 29 or less than 29. Use ≤ symbol
The difference of a number and ten is at least 91: The difference of a number and 10 is x-10. For at least we use ≥ because 91 is included.

Step-by-step explanation:
Answer:
800 inches³
Step-by-step explanation:
∵ The volume of each cube is s³
∵ The length of the side is 2 inches
∴ The volume of the cube = 2³ = 8 inches³
∵ The prism consists of 100 cubes
∴ The volume of the prism = 100 × 8 = 800 inches³
Another method:
We divide the number of cubes to form the rectangular prism
5 cubes as a length , 2 cubes as a width and 10 cubes as height
∵ The length of the side of each cube is 2 inches
∴ The length = 5 × 2 = 10 inches
∴ The width = 2 × 2 = 4 inches
∴ The height = 10 × 2 = 20 inches
∵ The volume of the prism = L × W × H
∴ V = 10 × 4 × 20 = 800 inches³
