Answer:

94 cm^2

Step-by-step explanation:

The surface area of a rectangular prism can be found using:

A=2(wl+hl+hw)

We know the width is 3, the height is 5, and the length is 4. We can substitute 3 in for w, 5 in for h, and 4 in for l.

A=2((3*4)+(5*4)+(5*3))

Multiply 3 and 4

A=2(12+(5*4)+(5*3))

Multiply 5 and 4

A=2(12+20+(5*3))

Multiply 5 and 3

A=2(12+20+15)

Add 12 and 20 and 15

A=2(47)

Multiply 2 and 47

A=94

So, the the surface area is 94 cm^2

The first three terms of a Fibonacci sequence are n 3n 4n find the sixth term I FB the sequence
Amiraneli [1.4K]

Answer:

<h2>18n</h2>

Step-by-step explanation:

In the Fibonacci sequence In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1.

Given data

First term= n

second term = 3n

third term = 4n

According to Fibonacci sequence the fourth term is

F4= F2 + F3\\F4=3n+ 4n= 7n

the Fifth term is

F5= f3 + f4\\f5= 4n+7n= 11n

hence  the sixth term is

F6= F4+F5\\   F6= 7n+11n= 18n

Use the function y=3/2x+3 to complete the table of values
anastassius [24]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

Putting all the values of y=9, 6, 0, and -3 to complete the table

FOR y=9

putting y=9

switch sides

subtract 3 from both sides

Hence,

when y=9, x=4

FOR y=6

putting y=6

switch sides

subtract 3 from both sides

Hence,

when y=6, x=2

FOR y=0

putting y=0

switch sides

subtract 3 from both sides

Hence,

when y=0, x=-2

FOR y=-3

putting y=-3

switch sides

subtract 3 from both sides

Hence,

when y=-3, x=-4

Hence, the table becomes:

x                     y

9                    4

6                    2

0                    -2

-3                   -4

What is the factorization of 729x^15 + 1000?
Tcecarenko [31]

Answer:

729x¹⁵ + 1000

This is a case of a sum of cubes.

729 is the cube of 9

1000 is the cube of 10

x¹⁵ is the cube of x⁵

A sum of perfect cubes can be factored into 

(a + b) (a² - ab + b²)

(9x⁵+ 10) ((9x⁵)²-(9x⁵)(10) + 10²)

(9x⁵ + 10) (81x¹⁰ - 90x⁵ + 100) THIS IS THE FACTORIZATION

9x⁵ (81x¹⁰ - 90x⁵ + 100) + 10(81x¹⁰ - 90x⁵ + 100)

729x¹⁵ - 810x¹⁰ + 900x⁵ + 810x¹⁰ - 900x⁵ + 1000

729x¹⁵ - 810x¹⁰ + 810x¹⁰ + 900x⁵ - 900x⁵ + 1000

729x¹⁵ + 1000
