Answer:
![+2n^5 - 9n^2 + 5n](https://tex.z-dn.net/?f=%2B2n%5E5%20-%209n%5E2%20%2B%205n)
Step-by-step explanation:
To solve the expression
![-n(-2n^4+9n-5)](https://tex.z-dn.net/?f=-n%28-2n%5E4%2B9n-5%29)
first we will multiply -n with each term and then find their products.
When doing multiplication the powers will be added and co-efficient will be multiplied.
![-n(-2n^4+9n-5)\\-n(-2n^4) -n(+9n) -n(-5)\\+2n^5 - 9n^2 + 5n](https://tex.z-dn.net/?f=-n%28-2n%5E4%2B9n-5%29%E2%80%8B%5C%5C-n%28-2n%5E4%29%20-n%28%2B9n%29%20-n%28-5%29%5C%5C%2B2n%5E5%20-%209n%5E2%20%2B%205n)

Answer:
7a^4 +35a^2 +28a
Step-by-step explanation:
Area is the product of height and width:
area = height × width
= 7 × (a^4 +5a^2 +4a)
area = 7a^4 +35a^2 +28a . . . . . . use the distributive property
Changing a fraction to its decimal form can be done by long division method. Dividing the denominator by its numerator will change the fraction into decimal form. Alternatively, you can use a calculator to do that for you. Below are the fractions with their decimal forms listed:
1.) 2/5 = 0.4 (D)
2.) 7/20 = 0.35 (A)
3.) 3/25 = 0.12 (C)
4.) 7/10 = 0.7 (B)
