Complete the steps to factor 56x2 – 8x – 7x + 1 by grouping.

group pairs of terms with common factors.
(56x2 – 8x) + (–7x + 1)

factor the gcf from each group.
8x(7x – 1) –1(7x – 1)

use the distributive property.
what is the factorization of the polynomial?

(8x – 1)(7x – 1)
(8x + 1)(7x – 1)
(8x + 7x)(1 – 1)

(8x-1)(7x-1) The question leaves you with the partially factored equation: 8x(7x-1) - 1(7x-1) look at the partially factored equation, you'll see that both terms have (7x-1) as one of their factors. take that (7x-1) as a factor and divide both terms by (7x-1), giving you (8x(7x-1) - 1(7x-1)) / (7x-1) The (7x-1) factors cancel out, leaving you with (8x - 1) So your 2 factors are (7x-1) and (8x-1). Looking at the available options, the only correct one is (8x-1)(7x-1)

A:  (8x-1) (7x-1)

Step-by-step explanation:

got it right on edge

good luck on the assignment

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
