Multiply the polynomial
(2c-1)(5c-7)
i just need to know how to do it!

For these questions, REMEMBER... FOIL or
First
Outside
Inside
Last

multiply both of the first terms 2c x 5c

then do the outsides of the terms 2c x -7

then the insides -1 x 5c

then the lasts -1 x -7

now add them all together

10 - 14c - 5c + 7 = 10 - 19c + 7

3units/ 5 feet = 60 units/ 100 feet3 units/ 5 feet = 18 units/ 30 feetthe dimensions of the scale drawing are 60 units by 18 units.hope this !
