Answer:

I will answer in English.

This can be translated to:

"Camila bought two books to read this vacation.  One is science fiction and the other is a novel.  If she finishes both books, she will have read 450 pages on vacation. The novel is known to have 60 pages  more than the science fiction book. Denoting by x  the number of pages in the fiction book and by y the number  pages of the novel book, it is possible to describe  a linear system with two equations involving x and  y with this information. "

First, the datat that we have is:

x + y = 450.

x + 60 = y.

Then we can isolate y in both equations, and have two linear equations:

y = 450 - x

y = x + 60.

Now we can graph those lines, and find the image bellow.

The point where the lines intersect is the solution of the system

We also can find the solution of the system as follows:

y = 450 - x = x + 60

then we can solve this for x.

450 - x = x + 60

2x = 450 - 60 = 390

x = 390/2 = 195

and we know that:

y = x + 60 = 195 + 60 = 255

Then: The science fiction book has 195 pages, and the novel has 255 pages.

A solução para os problemas levantados é:

1. O sistema linear com duas equações envolvendo as informações fornecidas é:

2. O gráfico que descreve este sistema no plano cartesiano pode ser encontrado como uma imagem anexa.

Obtenção e resolução do sistema de equações.

Levando em consideração que as variáveis ​​atribuídas são:  

A primeira frase menciona que se Camila terminar de ler os dois livros, ela terá lido 450 páginas, portanto, sabemos que a soma das páginas dos dois livros dará um total de 450, e na hora de escrever a equação:

Por outro lado, o depoimento diz que o livro de romance tem 60 páginas a mais que o livro de ficção, ou seja, o livro de ficção mais 60 páginas seria igual ao livro de romance, portanto, a equação seria:

Agora, você pode resolver o sistema de equações para ver o valor de x, substituindo a segunda equação na primeira:

Agora está calculado e com a segunda equação:

Desta forma, você pode ver que o livro de ficção científica tem 195 páginas, enquanto o romance tem 255 páginas.

Answer:

- x³ - 9x²

Step-by-step explanation:

Given

- (3x³ + x² ) + 2(x³ - 4x² ) ← distribute both parenthesis

= - 3x³ - x² + 2x³ - 8x² ← collect like terms

= - x³ - 9x²

The expression in the simplest form is -x³ - 9x².

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is - (3x³ + x² ) + 2(x³ - 4x² )  will be solved as below:-

E = - (3x³ + x² ) + 2(x³ - 4x² )

E = - 3x³ - x² + 2x³ - 8x²

E = - x³ - 9x²

Therefore, the expression in the simplest form is -x³ - 9x².

Answer:

Width is 20 inches.

Length is 44 inches.

Step-by-step explanation:

Recall that the perimeter of a rectangle is given by the formula:

[tex]P=2(l+w)[/tex]

Where l is the length and w is the width.

We know that the length is 4 more than double the width. In other words, we can write an equation for l:

[tex]l=4+2w[/tex]

Let's substitute this into the above equation. So:

[tex]P=2((4+2w)+w)[/tex]

Combine like terms:

[tex]P=2(4+3w)[/tex]

We are given that the perimeter is 128 (inches). So, substitute 128 for P and solve for w:

[tex]128=2(4+3w)[/tex]

Divide both sides by 2. The right side cancels:

[tex]64=4+3w[/tex]

Subtract 4 from both sides:

[tex]3w=60[/tex]

Divide both sides by 3:

[tex]w=20[/tex]

Therefore, our width is 20.

We can use the length formula we acquired previously to acquire length. We have:

[tex]l=4+2w[/tex]

Substitute 20 for w:

[tex]l=4+2(20)[/tex]

Multiply:

[tex]l=4+40[/tex]

Add:

[tex]l=44[/tex]

So, our length is 44.

And we width is 20.

And we're done!
