Answer:

0

Step-by-step explanation:

Separate into two parts

\frac{4xy^{3} }{2xy^{2} }  +  \frac{8x^{2} {y}^{5} }{2x {y}^{2} }

Simplify:

This is for the first fraction

\frac{4x {y}^{3} }{2x {y}^{2} }  = (4 \div 2)(x \div x)( {y}^{3}  \div  {y}^{2} )

2(1)( {y}^{3 - 2} )

2{y}

Now for the second fraction:

\frac{8 {x}^{2} {y}^{3}  }{2x {y}^{2} }  = ( 8 \div 2)( {x}^{2}  \div x)( {y}^{5}   \div   {y}^{2} )

4( {x}^{2 - 1} )( {y}^{5 - 2} )

4x {y}^{3}

Add both parts together

2y + 4x {y}^{3}

To turn this into the said formula, that would become:

2 {x}^{0}  {y}^{1}  + 4 {x}^{1}  {y}^{3}

Where:

a=0

b=1

c=1

d=3

Any value with an exponent 0 except zero will be equal to 1

We are to find the percentage increase of the weight of the puppy

We know that the formula of percentage increase if given by:

<em>Percentage increase = (new value - initial value)/initial value × 100</em>

So substituting the given values to get:

Percentage increase in puppy's weight = \frac{7.56-5.4}{5.4} \times 100 = 40%

How do you solve the first one
Dominik [7]

Answer:

x= -2  x=-2

Step-by-step explanation:

move over the leading coefficient and you get

3x²+12x+12

the pull out a 3 because that's your gcf and 3 cannot equal zero so you can just do without id and you get

x²+4x+4

and when you factor that you get

(x+2)(x+2)

and when you set those equal to zero you get x= -2 and x= -2
