Answer: 13.4 kilograms
Step-by-step explanation:
Because apples, bananas, and peaches are all fruits, all we need to do is add them together to find the total.
8.5 + 3 + 1.9 = 13.4
Be careful! Sometimes, the question will include objects that <em>aren't</em> fruits. Don't include those in your equation if it asks for the weight of the fruit (like in this question). That's extra information that you'll need to look out for in the future.
Don't forget your units (kilograms) and good luck!
The product of the given polynomials is:
![2a^4+5a^3-6a^2+19a-2](https://tex.z-dn.net/?f=2a%5E4%2B5a%5E3-6a%5E2%2B19a-2)
Step-by-step explanation:
Given polynomials are:
![a^2+3a-4\\and\\2a^2-a+5](https://tex.z-dn.net/?f=a%5E2%2B3a-4%5C%5Cand%5C%5C2a%5E2-a%2B5)
We will use the distributive property to multiply the polynomials
So,
![(a^2+3a-4)(2a^2-a+5)\\=a^2(2a^2-a+5)+3a(2a^2-a+5)-4(2a^2-a+5)\\=2a^4-a^3+5a^2+6a^3-3a^2+15a-8a^2+4a-20\\Combining\ like\ terms\\=2a^4-a^3+6a^3+5a^2-3a^2-8a^2+15a+4a-20\\= 2a^4+5a^3-6a^2+19a-2](https://tex.z-dn.net/?f=%28a%5E2%2B3a-4%29%282a%5E2-a%2B5%29%5C%5C%3Da%5E2%282a%5E2-a%2B5%29%2B3a%282a%5E2-a%2B5%29-4%282a%5E2-a%2B5%29%5C%5C%3D2a%5E4-a%5E3%2B5a%5E2%2B6a%5E3-3a%5E2%2B15a-8a%5E2%2B4a-20%5C%5CCombining%5C%20like%5C%20terms%5C%5C%3D2a%5E4-a%5E3%2B6a%5E3%2B5a%5E2-3a%5E2-8a%5E2%2B15a%2B4a-20%5C%5C%3D%202a%5E4%2B5a%5E3-6a%5E2%2B19a-2)
Hence,
The product of the given polynomials is:
![2a^4+5a^3-6a^2+19a-2](https://tex.z-dn.net/?f=2a%5E4%2B5a%5E3-6a%5E2%2B19a-2)
