Factor x3 – 7x2 – 5x + 35 by grouping. What is the resulting expression?

Step-by-step explanation:

Edge 2021

Polynomial is an expression that consists of indeterminates(variable) and coefficients. The correct option is A.

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

For the given expression x³ – 7x² – 5x + 35 the factorisation by grouping can be done as,

x³ – 7x² – 5x + 35

Take x² as common from the first two terms, while -5 as common from the last two terms,

= x²(x – 7) –5(x  – 7)

Take (x–7) as the common term from the two terms,

= (x² – 5)(x – 7)

Hence, the correct option is A.

[tex]k = \frac{m}{360} \times a[/tex]

Input the things which you already know. (m)

[tex]k = \frac{45}{360} \times a[/tex]

a=πr^2

a=36π

Input this into the equation.

Answer:

Step-by-step explanation:

 y^2 - 3y + 12

It has 3 terms (y^2) and (-3y) and (12)...therefore, it is a trinomial.

The degree of a polynomial with 1 variable is the highest exponent...so it has a degree of 2. But if it had more then 1 variable, it would be different.

answer is : trinomial with a degree of 2

The polynomial y² – 3y + 12 is trinomial with a degree of 2. Therefore, option C is the correct answer.

The given polynomial is y² – 3y + 12.

An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

Here, the polynomial y² – 3y + 12 is trinomial with a degree of 2

Therefore, option C is the correct answer.

Kendra spent one-third of allowance on a book and two-fifth on snack.

If she had four dollar remaining after purchase

Suppose x is the original amount

[tex]\therefore x-\dfrac{x}{3}-\dfrac{2x}{5}=4\\\\\Rightarrow \dfrac{15x-5x-6x}{15}=4\\\\\Rightarrow 4x=60\\\Rightarrow x=15[/tex]

Thus, 15$ was her total allowance.

B: The width of the vegetable bed is 5 feet. The length is 13 feet.

Answer:

133

Step-by-step explanation:

Because the figure is an irregular figure we need to break it up into two regular figures

The figure would be broken into..

A square with a side length of 4

And a rectangle with a length 13 and a width of 9

We now find the areas of the regular figures and add them together to get our answer

For the square.

To find the area of a square simply square the side length

Area = 4^2 = 16

For the rectangle

to find the area of the rectangle simply multiply the Length by the width

Area = 13*9= 117

Finally add the two areas together to get the area of the composite figure

117 + 16 = 133

Answer:

27 is the answer

Step-by-step explanation:

We have this proportion....

36 / 12 = x / 9 where x is the model door height

Cross-multiply

36*9 = 12 * x

324 = 12 *x divide both sides by 12

27 = x and that's the model height in centimeters

Answer:

The vertex of this problem is (8,16). This means that the highest height the ball reaches is at t = 8s, and this maximum height is of 16 feet.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].

b(x) = - 0.25 x^2 + 4x

Quadratic equation with [tex]a = -0.25, b = 4[/tex].

Vertex:

[tex]x_{v} = -\frac{4}{2(-0.25)} = 8[/tex]

[tex]\Delta = 4^2-4(-0.25)(0) = 16[/tex]

[tex]y_{v} = -\frac{16}{4(-0.25)} = 16[/tex]

The vertex of this problem is (8,16). This means that the highest height the ball reaches is at t = 8s, and this maximum height is of 16 feet.

Answer:

48 globos

Step-by-step explanation:

De la pregunta anterior, se nos dice que:

En el cumpleaños de Manolito se inflaron 144 globos.

Por eso:

Para globos rojos

2/9 de los globos eran rojos

Número de globos rojos = 2/9 × 144 globos

= 32 globos

Para globos verdes

5/18 eran verdes

Número de globos verdes = 5/18 × 144 globos

= 40 globos

Para globos amarillos

1/6 eran amarillas

Número de globos amarillos = 1/6 × 144 globos

= 24 globos

Tenga en cuenta que:

Número total de globos =

Globos rojos + Globos verdes + Globos amarillos + Otros colores

Otros colores = 144 globos - (globos rojos + globos verdes + globos amarillos)

Otros colores = 144 globos - (32 + 40 + 24) globos

= 144 globos - 96 globos

= 48 globos

Por lo tanto, la cantidad de globos que son de otros colores = 48 globos
