How do you simplify 4+6(7x+7)

Alright!

To simplify 4 + 6(7x + 7), we must combine like terms. Right off the bat, we can see what we have to do thanks to the order of operations.

* original equation
4 + 6(7x + 7)

* alright, so - since we can't do anything in the parenthesis, we now have to see what we can do multiplication wise.
4 + 42x + 42

* alright, so we could multiply the two 7's by 6, but now what? well, we can't do anything else to the 42x because of the variable, so we have to now add 4 and 46!

and our simplified equation is... 42x + 46! =)

How do you condense 2ln6 - ln3?

Ugo [173]

Ln(6)=ln(3^2)=2*ln(3)
so 2*ln(6) = 4*ln(3)

so 2*ln(6) - ln(3) = 3*ln(3)

What is the length of the hypotenuse of the triangle?

Jobisdone [24]

Essentially, we just use the pythagorean theorem to solve:

7^2 + 3^2 = c^2

49 + 9 = c^2

58 = c^2

c = sqrt 58

The answer is Option D.

Put these fractions in order least to greatest. 4/6 1/3 and 1/5

stiv31 [10]

Answer:

1/5 < 1/3 < 4/6

Step-by-step explanation:

Using the given inputs:

4/6 1/3 1/5

The least common denominator (LCD) is: 30.

Rewriting as equivalent fractions with the LCD:

4/6 1/3 1/5

20/30 10/30 6/30

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

1/5 1/3 4/6

6/30 < 10/30 < 20/30

Therefore, the sorted inputs in order from least to greatest is:

1/5 < 1/3 < 4/6

I am sketching parabolas and my book is telling me that I need only two points. But I don't know how I am meant to sketch the pa

Sever21 [200]

Answer:

In order to sketch a parabola, one will typically use the y-intercept, the x-intercepts, and the vertex.

Step-by-step explanation:

In order to sketch a parabola, one will typically use the given equation in standard form, $y = ax^2 + bx + c$ , and:

The y-intercept – the point where the parabola crosses the vertical axis – by substituting 0 for all x values in the given equation and solving for y.
The x-intercepts – the points where the parabola crosses the horizontal axis – by setting the given equation equal to 0 (i.e., y = 0) and finding the factors (or roots).
The vertex – the point of symmetry where the parabola changes direction and curves up or down – by using $x=\frac{-b}{2a}$ to find the x-coordinate then plugging that value into the given equation to find the y-coordinate.
