Factor completely. x 3 + 6x 2 - 4x - 24

1 answer:

You can factor (x^3 and 6x^2) and (-4x and -24).

So x^2(x+6) - 4(x+6)

(x^2-4)(x+6)

(x-2)(x+2)(x+6)

SOS PLEASE HELP <br>write the equation for this line <br>

Deffense [45]

If this is for slope-intercept, the equation is: y = 3x + 1

To find the slope, you would find the rise over run ( $\frac{rise}{run}$ ). So, you would start where the graph intersect at the y-axis, which is 1. You would go up 3 times, and right 1 time. So, $\frac{3}{1}$ , or 3, would be your slope. To find the y-intercept, you would need to find where the graph intersects at the y-axis, which is 1, so it would be your y-intercept. Plug them into the y = mx + b formula and the answer is <em>y = 3x + 1</em>.

Pls answer me this all question

Scorpion4ik [409]

Answer:

a. $5 \frac{21}{40}$

b. $\frac{1}{42}$

Step-by-step explanation:

$a. \: 12 \frac{2}{5} - 6 \frac{7}{8}$

$\frac{62}{5} - \frac{55}{8}$

$\frac{62}{8} \times \frac{8}{8} - \frac{55}{8} \times \frac{5}{5}$

$\frac{62 \times 8 - 55 \times 5}{40}$

$\frac{221}{40}$

$5 \frac{21}{40}$

$b. \: \frac{3}{14} - \frac{4}{21}$

$\frac{3}{14} \times \frac{3}{3} - \frac{4}{21} \times \frac{2}{2}$

$\frac{3 \times 3}{42} - \frac{4 \times 2}{42}$

$\frac{1}{42}$

Hope it is helpful....

Solve for x can someone please answer help

lakkis [162]

Answer:

Step-by-step explanation:

Similar triangles

$\frac{AD}{AB}=\frac{DE}{BC}\\\\\frac{x+2}{x}=\frac{3}{2}\\\\$

Cross multiply

2*(x+2) = 3*x

2x + 2*2 = 3x

2x + 4 = 3x

Subtract 2x from both sides

2x + 4 -2x = 3x - 2x

4 = x

x = 4
