What is the area of a square in terms of x & y, if one side is 2x-y?
Answers
Answer: (2x-y)^2
Step-by-step explanation:
The area of a square is given by the formula A = s^2.
We know that the length of one side is s = 2x-y. We can substitute this into our area equation:
A = (2x-y)^2
If you need to multiply out the answer:
A = (2x-y)(2x-y)
A = 4x^2-4xy+y^2

The value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The expression:
= 2d + 4d - 9 - 7
Plug d = 5 in the above expression:
= 2(5) + 4(5)- 9 - 7
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= 10 + 20 - 9 -7
= 30 - 16
= 14
Thus, the value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.

Iola has $75. She buys a pair of shoes on sale for one-half off and a pair of socks for $6. She has $32 left. Which equation can be used to find x, the regular price of the shoes?
Answers
Answer:
To solve for the problem above, let x be the regular price of the shoe.
1/2x is the one-half price of the shoe then we add 6 for the pair of socks,
1/2x + 6, then lola has 32 left so we add that too, 1/2x + 6 + 32 = 75. The total amount of lola spent is 75 - 32, which is 1/2x + 6.

I'VE ASKED THIS ONE EARLIER BUT NOBODY ANSWERED Point D is in the interior of \small \angle ABC, \small m\angle ABC=20x-15, \small m\angle ABD=6x-5, and \small m\angle DBC=x+16. What is \small m\angle ABD? \small m\angle ABD= degrees
Answers
Answer:
7°
Step-by-step explanation:
Since, Point D is in the interior of angle ABC.
Therefore,
[tex]m\angle ABC = m\angle ABD + m\angle DBC\\
20x - 15 = 6x - 5 + x + 16\\
20x - 15 = 7x + 11\\
20x - 7x = 11+15\\
13x = 26 \\ x = \frac{26}{13} \\ x = 2 \\ \\ m\angle ABD = (6x - 5) \degree \\ m\angle ABD = (6 \times 2 - 5) \degree\\ m\angle ABD = (12 - 5) \degree \\ \huge \red{ \boxed{ m\angle ABD = 7\degree}}[/tex]

You want to leave a nice tip on a $36 meal. So you decide to add 20% to the bill. How much is the total bill?
Answers
Answer:
43.20
Step-by-step explanation:
First find the tip
36 * 20 %
36 * .2
7.20
Then add the tip to the amount of the meal
36+7.20
43.20
You went to have a meal which costs $36, and maybe becoming very delighted with the taste and service of the food centre, you decided to add a tip.
[tex]20\%[/tex] of the total meal.So, First we need to find the tip by multiplying the percentage with the cost of meal
Tip:
[tex]20\% \: of \: 36[/tex]
[tex] \frac{20}{100} \times 36[/tex]
[tex] \frac{1}{5} \times 36[/tex]
[tex]7.2[/tex]
Now, we have got the amount of money we decided to give as a tip. And, we are already having the cost of meal. So, total money paid:
[tex]36 + 7.2[/tex]
[tex] \boxed{ 43.2}[/tex]
This is our required answer.

ariel Is making bracelets to sell at the stand during her school fall festival. she bought 15 1/6 and long and a 12 1/3. if each bracelet requires 1/2 of a foot of a string how many bracelets can aerial make
Answers
Number of bracelets she can make from 15 1/6 = 91/6 foot of string is :
[tex]n_1=\dfrac{\dfrac{91}{6}}{\dfrac{1}{2}}\\\\n_1=30.33[/tex]
So, number of bracelets from 15 1/6 foot string are 30.
Now,
Number of bracelets she can make from 12 1/3 = 35/3 foot of string is :
[tex]n_2=\dfrac{\dfrac{35}{3}}{\dfrac{1}{2}}\\\\n_2=23.33[/tex]
Number of bracelets from 12 1/3 foot string are 23.
Therefore, total number of bracelets she can make is 23 + 30 = 53.
Hence, this is the required solution.
