Answer:

He can fit 2 more DVD's on the shelf.

And he'll have about 12 mm of extra space left.

Step-by-step explanation:

40×1.4 = 56cm This is the length of space the 40 DVD's will take up.

60-56 = 4cm This is the amount of space left.

4/1.4 = 2.857 the number of DVD's that will fit.

Of course, the decimal represents a partial DVD which is worthless.

Just to be sure, 2×1.4 = 2.8cm OK. But 3×1.4= 4.2cm which is 2mm too much

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

konstantin123 [22]

The factorization of the polynomial $56x^2-8x-7x+1$ is $(8x-1)(7x-1)$

Step-by-step explanation:

We need to Complete the steps to factor $56x^2-8x-7x+1$ by grouping.

After grouping:

$(56x^2-8x) + (-7x + 1)$

Factor the GCF from each group.

$8x(7x-1)-1(7x-1)\\$

Use the distributive property.

$(8x-1)(7x-1)$

So, the factorization of the polynomial $56x^2-8x-7x+1$ is $(8x-1)(7x-1)$
