Mathematics
1 answer:
Anton [14]2 years ago
6 0

Answer:

Step-by-step explanation:

(3x+4)(x^2+px+5) \\=3x^3+3px^2+15x+4x^2+4px+20\\=3x^3+(3p+4)x^2+(15+4p)x +20

since we know that x^2  in this expansion is -23x^{2}

thus 3p+4=-23\\3p=-27\\p=-9

Hope that helps!

Hi there,
Mrrafil [7]
We have 7 people which result ----> 7 * <u />2 = <u>14 legs</u>

Also, the table has <u>4 legs</u>

The number of the big cats is 7 *7 =49 (big cats)

For every big cat we have ---> 49 * 4= <u>196 legs</u>

For every big cat we have 7 small cats which means --> 49 * 7= 343 (small kittens)

The number of legs for small kittens is 343 * 4 = <u>1372 legs</u>

The number of legs is:
<u />
<u>14+4+196+1372= 1586 legs are in total</u>

A mechanic is using a machine that makes metal parts. She measures each part to confirm it is the correct size. Negative numbers
Hunter-Best [27]

Answer:

A

Step-by-step explanation:

In the figure attached, the complete question is shown.

We have to transform all the fractions to new fractions with the same denominator, as follows:

1/8 *4/4 = 4/32

-3/16 *2/2 = -6/32

-1/4 *8/8 = -8/32

1/32

5/32

-1/16 *2/2 = -2/32

Now we can order the list simply comparing numerators:

-8/32, -6/32, -2/32, 1/32, 4/32, 5/32

or

-1/4, -3/16, -1/16, 1/32, 1/8, 5/32
