Which model represents the factors of X^2+9x+8

NeX [460]

Answer:

The models have tiles corresponding to x+8 and x+1

Step-by-step explanation:

We want to find the model that represents factors of

${x}^{2} + 9x + 8$

We split the middle term to get:

${x}^{2} + 8x + x + 8$

We factor by grouping to obtain:

$x(x + 8) + 1(x + 8)$

We collect common factors again to get:

$(x + 8)(x + 1)$

The models have tiles corresponding to x+8 and x+1

How many different books did the children read

Alex777 [14]

Answer:

16 books

Step-by-step explanation:

if Sandra read 5 books and Deacon read 6 and Breanna read 7 and they all one same book, then that means sandra read 4 different books then Deacon and Breanna. Deacon read 5 different books then Sandra and Breanna. Breanna read 6 different books then Deacon and Sandra.

So Sandras 4 books plus Deacons 5 books plus Breannas 6 books equals up to 15 but, now you need to add the one book they all read which makes the answer 16.

(Hopes this helps)
