How to factor this expression x^3 - 4x^2 + 4x - 16

Natalija [7]

X²(x - 4) +4 (x - 4)

(x² + 4) (x - 4)

First find the common terms that can enter into both x³ and 4x² then write its down in this case it’s x² that can enter x³ leaving only x _since x³/x² = subtract of the indices. x² will also enter 4x² leaving only four hence you having x² (x - 4)
then do the same for the next pair of terms giving you 4 that can enter into both 4 and 16
Leaving you with +4 (x - 4)

Now you can put the common terms together like so (x² + 4) and choose get one of the other two which are the same= (x - 4)
= (x² + 4) (x - 4)

The ratio of the number of dogs to the number of cats is 4:5. There are 270 animals on the rescue farm. for each of the followin

romanna [79]

Answer:

see the procedure

Step-by-step explanation:

Let

x ----> the number of dogs

y ---> the number of cats

we know that

The ratio of the number of dogs to the number of cats is 4:5

$\frac{x}{y}=\frac{4}{5}$

$x=\frac{4}{5}y$ ----> equation A

That means ---> The number of dogs is 4/5 the number of cats

There are 270 animals on the rescue farm

$x+y=270$ ----> equation B

Substitute equation A in equation B

$\frac{4}{5}y+y=270$

solve for y

$\frac{9}{5}y=270$

$y=270(5)/9\\y=150\ cats$

Find the value of x

$x=\frac{4}{5}(150)=120\ dogs$

Verify each statement

a) The number of dogs is 4/5 the number of cats

The statement is true (see the explanation)

b) 4/5 of the pets at the farm are dogs

The statement is false

Because

(4/5)(270)=216 dogs

The number of dogs is 120 not 216 (see the explanation)

c) There are exactly 30 more cats than dogs

The statement is true

Because, there are 150 cats and 120 dogs (see the explanation)

d) There are exactly 30 dogs at the farm

The statement is false

Because, there are 120 dogs in the farm (see the explanation)

e) 5/9 of the pets at the farm are cats

The statement is true

Because

(5/9)270=150 cats

The number of cats is 150 (see the explanation)

I have no idea what the answer is , plz help

natima [27]

1/3 of 1/4 is the same as 2/6 of 2/8
(easier for me this way)
2/6 is 0.33
2/8 is 0.25 so you are in essence finding roughly 0.8333
that would be equal to the diagram at the bottom right
The other question is (i believe) 1/5 of 5/6
1/5 is 0.2, 5/6 is 0.833
another way to do it is to divide 833 by 5 is 166.6 so it would be 0.166
that would (i think) be the top right
