When ordering a student desk priced at $69.00, the shipping charges are 6%. What is the total cost of the desk?

Wittaler [7]

Since the desk is $69.00 and the shipping charges are 6%

69*.06= 4.14

Your tax would be $4.14 so,

$4.14+$69.00= A total of $73.14

Jan is x years old, her sister is twice as old as her, and her brother is three times older than her. Their ages add up to 29. H

victus00 [196]

Jan's age = $4\frac{5}{6}$ years

Sister's age = $9\frac{2}{3} \: years$

Step-by-step explanation:

Jan's age = x years

Sister's age = 2x years

Brother's age = 3x years

According to the given condition:

x + 2x + 3x = 29

6x = 29

x = 29/6

x = $4\frac{5}{6}$ years

2x = $2\times \frac{29}{6}= \frac{29}{3}=9\frac{2}{3} \: years$

Therefore,

Jan's age = $4\frac{5}{6}$ years

Sister's age = $9\frac{2}{3} \: years$

PLEASE MATH EXPERT! <br> I am struggling thank you

Answer:

$x^{4} -y^{4} +6x^{2}y+9y^{2}$

Step-by-step explanation:

This is just a big multiplication, but it gets more simple when you break it into steps.

First consider $x^{2} (x^{2} +3y-y^{2} )$ . This multiplies out to $x^{4} +3x^{2}y-x^{2}y^{2}$

Next, $3y(x^{2} +3y-y^{2} )$ . This is $3x^{2}y+9y^{2}-3y^{3}$

Finally, $y^{2} (x^{2}+3y-y^{2})$ . This is $x^{2}y^{2} +3x^{3}-y^{4}$

Sum these three expressions together and you get $x^{4} -y^{4} +6x^{2}y+9y^{2}$
