What is (-7a^4bc^3)(5ab^4c^2)

-35a^5b^5c^7

Step-by-step explanation:

Step 1:  Distribute

(-7a^4bc^3)(5ab^4c^4)

(-7 * 5) * (a^4 * a) * (b * b^4) * (c^3 * c^4)

(-35) * (a^5) * (b^5) * (c^7)

-35a^5b^5c^7

 -35a^5b^5c^7

is this a multiple choice question?

if so it's a and c

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
