Factor the expression P^4+3p^3-10p^2
bonufazy [111]

Answer:

p^2(p+5)(p-2)

Step-by-step explanation:

To begin factoring the expression p^4+3p^3-10p^2, we use the GCF or greatest common factor. The greatest common factor is the greatest number that will divide into two or more values. We start to find it by factoring each term:

p^4=p*p*p*p

3p^3: 3*p*p*p

-10p^2: -10*p*p

Remember -10 can factor into smaller numbers but since it doesn't have common factors with the others, we've chosen to leave it as -10.

We notice the only common factors bare p*p or p^2.

We write in the form p^2(____+_____+_____). We find the inside of the parenthesis by dividing each term by p^2.

\frac{p^4}{p^2} =p^2

\frac{3p^3}{p^2} =3p

\frac{-10p^2}{p^2}=-10

p^2(p^2+3p-10).

We are not finished yet. We have a trinomial (3 terms) which also factors. We factor by splitting the middle term 3p into factors of -10 which add to 3.

--10 = 5 * -2

3p= 5p +-2p

We write p^2(p+5)(p-2).

There are 100 dogs at Pampered Paws Kennel. Each day, the dogs eat 100 lb of food. Large dogs eat 3 lb, medium dogs eat 2 lb, an
UNO [17]
The answer is 5 large, 25 medium, 70 small dogs.

x - the number of large dogs
y - the number of medium dogs
z - the number of small dogs

<span>There are 100 dogs at Pampered Paws Kennel:
</span>x + y + z = 100

<span>Each day, the dogs eat 100 lb of food. Large dogs eat 3 lb, medium dogs eat 2 lb, and small dogs eat 0.5 lb:
3x + 2y + 0.5z = 100

</span><span>There are five times as many medium dogs as large ones:
x = 5y

</span>x + y + z = 100
3x + 2y + 0.5z = 100
y = 5x
____
Substitute y in the first two equations:
x + 5y + z = 100
3x + 2*5x + 0.5z = 100
___
6x + z = 100
13x + 0.5z = 100
____
z = 100 - 6x
13x + 0.5z = 100
____
13x + 0.5(100 - 6x) = 100
13x + 50 - 3x = 100
13x - 3x = 100 - 50
10x = 50
x = 50/10 = 5

y = 5x = 5 * 5 = 25

x + y + z = 100
5 + 25 + z = 100
30 + z = 100
z = 100 - 30
z = 70

Fantom [35]

Answer:

Step-by-step explanation:Answer:

1cm = 50

2 cm = 50 x 2

3cm = 50 x 3

and the inverse:50m = 50/50 = 1cm

100m = 100/50 = 2cm

150m = 150/50 = 3cm

381m = 381/
