Answer:

Step-by-step explanation:

Because first you need to make the equation negative because X^2 need to be positive (easier to do)

x^2-6x-m

What times to -6 are

(2times-3) (-2 times -3)

(1times -6) and (-1times 6)

neither of these will be above 9 so d is correct

Answer:

$\huge \boxed{2\sqrt{5} +\sqrt{35}}$

Step-by-step explanation:

$\sqrt{5} (2+\sqrt{7} )$

Expand brackets.

$\sqrt{5} (2)+\sqrt{5}(\sqrt{7} )$

$2\sqrt{5} +\sqrt{5} \sqrt{7}$

Apply radical rule : $\sqrt{a} \sqrt{b} =\sqrt{ab}$

$2\sqrt{5} +\sqrt{5 \times 7}$

$2\sqrt{5} +\sqrt{35}$

ELEN [110]

Answer:

$12^{11}$

Step-by-step explanation:

12 has the exponent of 11

12 is the base

^11 is the exponent

since 12 is multiplied by itself 11 times, so that means we will have the exponent of 11...

Hello, happy Friday, I am just here with some geometry questions.

Genrish500 [490]

Answer:

$x=4$

Step-by-step explanation:

By the Triangle Proportionality Theorem:

$\displaystyle \frac{x}{12}=\frac{x+1}{15}$

By cross-multiplication:

$\displaystyle 12(x+1)=15(x)$

Distribute:

$12x+12=15x$

Subtract 12x from both sides:

$12=3x$

Hence:

$x=4$

13 POINTS PLZ HELP!!

Vitek1552 [10]

Answer:

Slope: -10

Y-intercept: 50

X-intercept: 5

Step-by-step explanation:

y-mx+b

y=-10x+50

m is slope so, slope is -10

plug in 0 for x and solve to get y-intercept y=-10(0)+50 , y intercept is 50
plug in 0 for y and solve to get x-intercept 0=-10x+50, x-intercept is 5
