I am assuming it's asking this? I'm not too sure.
Answer:
[tex](4b - 5 {)}^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² - 2ab + b², where a = 4b and b=5.
[tex](4b)^{2} - 2(4b)(5) + {5}^{2} [/tex]
2) Use square of Difference: (a - b)² = a² - 2ab + b².
[tex](4b - 5)^{2} [/tex]

Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una. ¿Cuánto pagó por todo?
Answer:
Costo Total= $38,680
Step-by-step explanation:
Dada la siguiente información:
Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una.
Para calcular el costo total, debemos usar la siguiente formula:
Costo Total= costo unitario * cantidad adquirida
Costo Total= 408*16 + 732*27 + 652*19
Costo Total= $38,680
The total amount of everything including sewing machines, sound systems, and washing machine is $38,680.
What is the cost price?The cost price refers to the original price of the items, it is the total amount of money that costs a manufacturer to provide a given product.
The unit cost of sewing machines = 408
The unit cost of a sound system = 732
The unit cost of a washing machine = 652
Total cost = 408 × 16 + 732 × 27 + 652 × 19
= 6528 + 19764 + 12388
= $38,680
Therefore, the total amount of everything including sewing machines, sound systems, and washing machine is $38,680.

What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
a. 16 feet by 16 feet:
The width of the room on the scale drawing will be 16/1.5 = 10.67 inches, and the length will also be 10.67 inches. Since both dimensions are greater than the width and length of the paper, the scale drawing will not fit on one piece of paper.
Answer: No.
b. 10 feet by 15 feet:
The width of the room on the scale drawing will be 10/1.5 = 6.67 inches, and the length will be 15/1.5 = 10 inches. The length dimension of the scale drawing fits on the paper, Therefore, the scale drawing will fit on one piece of paper.
Answer: Yes.
c. 15 feet by 20 feet:
The width of the room on the scale drawing will be 15/1.5 = 10 inches, and the length will be 20/1.5 = 13.33 inches. Both dimensions are greater than the width and length of the paper, so the scale drawing will not fit on one piece of paper.
Answer: Not.
d. 12 feet by 16 feet:
The width of the room on the scale drawing will be 12/1.5 = 8 inches, and the length will be 16/1.5 = 10.67 inches. Both dimensions are less than the width and length of the paper, so the scale drawing will fit on one piece of paper.
Answer: Yes.

A group of 5 friends went to the movies. A bag of popcorn costs $2.99. How much will it take cost to get one bag of popcorn for each friend
Answer:
this one is so simple add $2.99 5 times
Step-by-step explanation:
Answer:
14.95
Step-by-step explanation:
I guess you are assuming that one person is getting the popcorn for all 5 people including themselves. It's not worded the best way I've ever seen but that is the assumption I will make
So you multiply 5 * 2.99 = 14.95
Only for interest's sake, you could solve the question by multiplying by 5 * 3 dollars
5 * 3 = 15 dollars
You take off 5 cents because the actual cost is 2.99 and that is 1 cent below 3 dollars.
15.00 - 05 = 14.95 or a nickel less than 15 dollars.

Find f(-5) if f(n) = n^3 + 3n^2
what is the exact volume of a cylinder with a radius of 7 inches and a height of 20 inches
Answer:
V = 3078.76 in³
Step-by-step explanation:
To find the volume of a cylinder, use this formula:
V = πr²h
V = volumer = radiush = heightPlug in the values you know.
V = π(7)²(20)
First let's evaluate the exponent.
7² = 49
V = π(49)(20)
Now let's multiply.
49 • π = 153.938
153.938 • 20 ≈ 3078.76
V = 3078.76 in³
This is your answer.

Answer:
Blank 1: y=3x+10
Blank 2: y= 40
Step-by-step explanation:
Let the cost of gift wrap be y and the number of gifts be x.
Department
An upfront fee of $10 means that Mr Bentley needs to pay $10 first, and this $10 is only paid once on top of the cost of wrapping each gift.
y= 3x +10
Niece
A flat fee of $40 means that no matter how many gifts the niece wraps, Mr Bentley only pays $40.
y= 40
To find out when the two plans cost the same, equate the two equations together. Then, solve for x.
3x +10= 40
3x= 40 -10 (-10 on both sides)
3x= 30
x= 30 ÷3
x= 10
Thus when Mr Bentley has 10 gifts to be wrapped, the 2 plans costs the same.
(x - 1)-+ x (1 - x)
-
-(1+x)
--x-1
