It is $84.6. You multiply 1.6 by 13 which equals $20.8. Then you multiply 3.1 by 14 which equals $43.4. Then you multiply 1.2 by 17 which equals $20.4. Add them together and you get $84.6.

Answer:
10x^2-25x-35
Step-by-step explanation:
FOIL means first, outer, inner, and last.
The first term of each pair is 2x and 5x.
The outer term of each pair is 2x and 5.
The inner term of each pairs are -7 and 5x.
The last term of each is -7 and 5.
Now we just have to multiply the terms I pairs above:
First: (2x)(5x)=10x^2
Outer: (2x)(5)=10x
Inner: (-7)(5x)=-35x
Last: (-7)(5)=-35
------------------------------Add the terms:
10x^2-25x-35
