Answer: 27
Step-by-step explanation: To evaluate this expression, we will need to plug in the value of "z" to get our answer. In this problem, we are given that "z" is equal to 3 so we will multiply 9 by 3 which equals 27.
Answer:
The volume = 
Step-by-step explanation:
* The rule of the volume of the rectangular prism:
- the volume of any prism = base area × height
∵ The base of the rectangular prism is rectangle
∵ Area any rectangle = Length × Width = l × w
∴ The volume of the rectangular prism = l × w × h
* In the problem:
∵ l = x , w = x² , h = 5x² + 4x + 1
∴ The volume = (x)(x²)(5x² + 4x + 1)
* We will simplify it
- Multiply x by x² and then multiply the answer by the bracket
∵ x × x² = x³
∴ x³(5x² + 4x + 1)
∵ x³ × 5x² = 5x^5
∵ x³ × 4x = 4x^4
∵ x³ × 1 = x³
∴ The volume = 
Knowing that one dime has a 10 cent value and that a nickle has a 5 cent value, we can use multiplication or addition to find the answer.
5 x 10 = 50 5 dimes together are worth 50 cents.
2 x 5 = 10 2 nickles together are worth 10 cents.
50 + 10 = 60 5 dimes and 2 nickles are worth 60 cents when added together.
ANSWER: Aaron has 60 cents.
There's 12 months in a year so if the value decreases by 6% each year that would be 6 ÷ 12 which is 0.5%. Therefore the decay each month is -0.5%.
