Answer:
[tex]\displaystyle \frac{100}{81}m^8p^{12}q^{16}z^2-\frac{20}{63}m^5p^7q^8z^5+ \frac{1}{49}m^2p^2z^8=\left(\frac{10}{9}m^4p^{6}q^{8}z-\frac{1}{7}mpz^4\right)^2[/tex]
Step-by-step explanation:
Trinomio Cuadrado Perfecto
El producto notable llamado cuadrado de un binomio se expresa como:
[tex](a-b)^2=a^2-2ab+b^2[/tex]
Si se tiene un trinomio, es posible convertirlo en un cuadrado perfecto si cumple con las condiciones impuestas en la fórmula:
* El primer término es un cuadrado perfecto
* El último término es un cuadrado perfecto
* El segundo término es el doble del proudcto de los dos términos del binomio.
Tenemos la expresión:
[tex]\displaystyle \frac{100}{81}m^8p^{12}q^{16}z^2-\frac{20}{63}m^5p^7q^8z^5+ \frac{1}{49}m^2p^2z^8[/tex]
Calculamos el valor de a como la raiz cuadrada del primer término del trinomio:
[tex]\displaystyle a=\sqrt{\frac{100}{81}m^8p^{12}q^{16}z^2}[/tex]
[tex]\displaystyle a=\frac{10}{9}m^4p^{6}q^{8}z[/tex]
Calculamos el valor de a como la raiz cuadrada del primer término del trinomio:
[tex]\displaystyle b=\sqrt{\frac{1}{49}m^2p^2z^8[/tex]
[tex]\displaystyle b=\frac{1}{7}mpz^4[/tex]
Nos cercioramos de que el término central es 2ab:
[tex]\displaystyle 2ab=2\frac{10}{9}m^4p^{6}q^{8}z\frac{1}{7}mpz^4[/tex]
Operando:
[tex]\displaystyle 2ab=\frac{20}{63}m^5p^7q^8z^5[/tex]
Una vez verificado, ahora podemos decir que:
[tex]\displaystyle \frac{100}{81}m^8p^{12}q^{16}z^2-\frac{20}{63}m^5p^7q^8z^5+ \frac{1}{49}m^2p^2z^8=\left(\frac{10}{9}m^4p^{6}q^{8}z-\frac{1}{7}mpz^4\right)^2[/tex]

A restaurant starts with 10 dozen
pieces of cornbread. Every order
receives 2 piece of cornbread. At the
end of their lunch rush, there are 28
pieces of cornbread left. How many
orders did the restaurant take?
Answer:
46 orders.
Step-by-step explanation:
(10*12) - 2x = 28
120 - 2x = 28
-2x = 28 - 120
-2x = -92
x = -92/2
x = 46
which expression is equivalent to 15 - 5x? select all that apply
A -5(x - 3)
B 3(5-x)
C -5(3- x)

Given that the table shows the maximum daily temperatures, in degrees Fahrenheit, recorded in a Texas town in May.
84 86 84 88 83 85 90 84 88 84 85 83 85 84 90 84 85 85 83 85
In ascending order,

Median = middle entry =85
Histogram is the one which can be used to find the median of the maximum daily temperature.
THe median divides the histogram into two equal parts

Ann drove 638 miles in 11 hours.
At the same rate, how many miles would she drive in 9 hours?
Answer:
638 miles / 11 hours = 58mph
So if he is traveling at 58 miles per hour for 7 hours, multiply the two numbers. 7(58) = 406
At the same rate of speed, Eric would travel 406 miles in 7 hours.
Step-by-step explanation:
I hope you undertand it
Answer:
522
Step-by-step explanation:
638 miles.......11hours
x miles ............ 9 hours
x = 638 * 9 / 11 = 522 miles

Solve for g. If you can please add an explanation
Answer:
g=7
Step-by-step explanation:
your goal is to isolate the g
times g/-4 by -4/1 the -4 cancels out the other one so you are just left with g
move the g to the other side of the equation then move the 3 and it to the -5 and then multiply the whole thing but -1 to make the equation positive

You prepare 10 scoops of dog food for 5 dogs, and prepare 16 scoops of dog food for 8 dogs. What
is the constant of proportionality for the amount of dog food to the number of dogs? How many
scoops of dog food should you prepare for 6 dogs?
Answer:
12 scoops of dog food are needed for 6 dogs,
Step-by-step explanation:
Proportions
The number of scoops of dog foods and the number of dogs are proportional variables.
We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.
We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.
Thus, the constant of proportionality is 2.
For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.
12 scoops of dog food are needed for 6 dogs,

what's the slope between (5,-2) and (-7,22)
Answer: The answer is: -2
Step-by-step explanation:
Here, suppose
(5,-2)=(x1, y1)
(-7,22)=(x2, y2)
Now, use the slope equation to find slope(m).
y2-y1=m(x2-x1)
or,m=y2-y1/x2-x1
After this, just substitute the values from above.
At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x
what is the equation of the line
Answer:
