The numbers you use are
13.5 +13.5 +3 = 30
This is allowed because you can use any number and you can also repeat and in Brazil they right their decimals as 13,5 but in America it’s 13.5

What is the completely factored form of x3 â€"" 64x? x(x â€"" 8)(x â€"" 8) (x minus 4) (x squared 4 x 16) x(x â€"" 8)(x 8) (x â€

Vadim26 [7]

The factored form of an equation is done by rewriting the equation in simpler forms.

The completely factored form of $x^3 - 64x$ is $x(x-8)(x + 8)$

The expression is given as:

$x^3 - 64x$

Factor out x from the expression, $x^3 - 64x$

$x^3 - 64x = x(x^2-64)$

Express 64 as 8^2

$x^3 - 64x = x(x^2-8^2)$

Express the expression as a difference of two squares

$x^3 - 64x = x(x-8)(x + 8)$

Hence, the completely factored form of $x^3 - 64x$ is $x(x-8)(x + 8)$

IL GIVE YOU BRAINLIST !! * have to get it right * An equation for the line graphed is

Otrada [13]

Answer:

y = 3/2x+3

Step-by-step explanation:

The y intercept is 3. That is where it crosses the y axis

The slope is

m= (y2-y1)/(x2-x1) and we have points(0,3) and (-2,0)

= (0-3)/(-2,0)

=-3/-2

=3/2

Using the slope intercept form of a line

y = mx +b where m is the slope and b is the y intercept

y = 3/2x+3

Use the diagram and information to answer the question.

Answer:There are six important properties of parallelograms to know:

Opposite sides are congruent (AB = DC).

Opposite angels are congruent (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The diagonals of a parallelogram bisect each other.

Hope this helps!! :)

in mr carrs math class, 9 of the 14 said they like math , and 7 of the 16 boys said they like math . if miss carr randomly a sel

erma4kov [3.2K]

For the 1st fraction, since 14 × 1 = 14,

9 × 1

14 × 1

Likewise, for the 2nd fraction, since 7 × 2 = 14,

6 × 2

7 × 2

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

What is the equation of the line that passes through the points (6,8) and (-3,2)

Vikki [24]

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (6, 8) and (-3, 2). Substitute:

$m=\dfrac{2-8}{-3-6}=\dfrac{-6}{-9}=\dfrac{2}{3}\\\\y-8=\dfrac{2}{3}(x-6)\qquad|\text{use distributive property}\\\\y-8=\dfrac{2}{3}x-4\qquad|+8\\\\y=\dfrac{2}{3}x+4\qquad|-\dfrac{2}{3}x\\\\-\dfrac{2}{3}x+y=4\qquad|\cdot(-3)\\\\2x-3y=-12$

Answer:

point-slope form: $y-8=\dfrac{2}{3}(x-6)$

slope-intercept form: $y=\dfrac{2}{3}x+4$

standard form: $2x-3y=-12$
