(PLS HELP ) Find the product of

(−3y+1)(4y2−y−7).

-12y²+7y²+20y-7

Step-by-step explanation:

Here, we need to use the concept of the FOIL method

Given

 (-3y+1)(4y²-y-7)

Expand Parenthesis using FOIL

-12y³+3y²+21y+4y²-y-7

Put like terms together

-12y³+(3y²+4y²)+(21y-y)-7

Combine like terms together

-12y²+7y²+20y-7

Hope this helps!! :)

Please let me know if you have any questions

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
