Choose the product. -7p3(4p2 + 3p - 1)

21 p3 + 8 p2 + 3 p4 - 8 p
28 p6 + 21 p3 - 7 p
-28 p5 - 21 p4 + 7 p3
-21 p5 + 8 p4 - 3 p3

Option C - (-28p⁵-21p⁴+7p³)

Step-by-step explanation:

=> -7p³×4p²= -28p⁵ 1

=> -7p³×3p= -21p⁴ 2

=> -7p× (-1)= 7p³ 3p

Add 1+2+3

=> (-28p⁵-21p⁴+7p³)

Hope this helps you.

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )
