that's the formula of volume

Answer:

A. 9h

Step-by-step explanation:

The formula for the volume of a cube is:

side * side * side.

We know that each side is the same length, and we know all the sides, but this question has a variable for one side of the cube.

So, we get 3 * 3 * h which is 9h.

Answer:

A. because it doesn't change as it is going up, up, up, and so on.

Answer:

Step-by-step explanation:

It will be easier if you bring that binomial in-front, imo. But the main thing you want to do here is actually really easy. You have to distribute that x to every single term in the trinomial, then do the same thing for the 5. Add up everything.

Distribute the x and 5 like this:

[tex]x(2x^2+7x-10) + 5(2x^2+7x-10)[/tex]

[tex]2x^3+7x^2-10x+10x^2+35x-50[/tex]

Now combine like terms:

[tex]2x^3+17x^2+25x-50[/tex]

There's your answer. Btw, standard form means the exponents are in order high to low and all variables before constants

The product of the expression is 2x³ + 17x² + 25x - 50.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2x² + 7x - 10 and x + 5

Multiply both expressions.

(2x² + 7x - 10) x (x + 5)

2x³ + 10x² + 7x² + 35x - 10x - 50

Combine like terms.

2x³ + 17x² + 25x - 50

Thus,

The expression is 2x³ + 17x² + 25x - 50.

Answer:  [tex]x^2+y^2=\dfrac{105\pm 18\sqrt6}{2}[/tex]

Step-by-step explanation:

EQ1:  x + y = 12     --> x = 12 - y

EQ2:  xy = 15      

Substitute x = 12-y into EQ2 to solve for y:

(12 - y)y = 15

12y - y² = 15

0 = y² - 12y + 15

    ↓     ↓         ↓

  a=1   b= -12   c=15

[tex].\ y=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\\.\quad =\dfrac{-(-12)\pm \sqrt{(-12)^2-4(1)(15)}}{2(1)}\\\\\\.\quad =\dfrac{12\pm \sqrt{144-120}}{2}\\\\\\.\quad =\dfrac{12\pm \sqrt{24}}{2}\\\\\\.\quad =\dfrac{12\pm 2\sqrt{6}}{2}\\\\\\.\quad =6\pm \sqrt{6}[/tex]

Now, let's solve for x:

[tex]xy=15\\\\x(6\pm\sqrt6)=15\\\\x=\dfrac{15}{6\pm\sqrt6}\\\\\\x=\dfrac{15}{6\pm\sqrt6}\bigg(\dfrac{6\pm\sqrt6}{6\pm\sqrt6}\bigg)=\dfrac{6\pm \sqrt6}{2}[/tex]

Lastly, find x² + y² :

[tex]y^2=(6\pm \sqrt6)^2\quad \rightarrow \quad y^2=36\pm 12\sqrt6 +6\quad \rightarrow \quad y^2=42\pm 12\sqrt6[/tex]

[tex]x^2=\bigg(\dfrac{6\pm \sqrt6}{2}\bigg)^2\quad \rightarrow \quad x^2=\dfrac{42\pm 12\sqrt6}{4}\quad \rightarrow \quad x^2=\dfrac{21\pm 6\sqrt6}{2}[/tex]

[tex]x^2+y^2=\dfrac{21\pm 6\sqrt6}{2}+42\pm 12\sqrt6\\\\\\.\qquad \quad = \dfrac{21\pm 6\sqrt6}{2}+\dfrac{84\pm 24\sqrt6}{2}\\\\\\. \qquad \quad = \dfrac{105\pm 18\sqrt6}{2}[/tex]

Step-by-step explanation:

So, if x is length, then x*x*8 is 1568. To solve, you do 1568/8, which gives you 196. The square root of 196 is 14, and 14*14*8 is 1568.  

Answer:

4.138138=469069/500000

Step-by-step explanation:

The reason why Leslie is wrong is because: D. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

This ultimately implies that, a linear function is typically used for uniquely mapping an input variable to an output variable, with the pair of points having a constant of proportionality.

Mathematically, the rate of change can be calculated by using this formula;

Rate of change = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change = (y₂ - y₁)/(x₂ - x₁)

Rate of change = (-3 - (-4))/(0 - (-1))

Rate of change = 1/1

Rate of change = 1

For the other points chosen, the rate of change is given by:

Rate of change = (5 - (-3))/(2 - (-1))

Rate of change = 8/2

Rate of change = 4.

In conclusion, Leslie is wrong is because the rate of change or constant of proportionality for these data points are not the same.

Complete Question:

Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (-1, -4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (-1, -4) and (0, -3) to be (-3 - (-4))/(0 - (-1)) = 1 and the rate of change between the points (0, -3) and (2, 5) to be (5 - (-3))/(2 - (-1)) = 8/2 = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong?

Answer: x = 0

Step-by-step explanation:

Take it slow and do one problem at a time. Multiply the first x by the second ( ) and then move on to -3

2x + 9x -3x -27 = -27

combine all like terms

8x - 27 = -27

add 27 to both sides

8x = 0

divide by 8 to get x alone

x = 0

Answer:

x = -7

Step-by-step explanation:

Step 1: Write equation

3x - 1 = -22

Step 2: Add 1 on both sides

3x = -21

Step 3: Divide both 3

x = -7
