Answer:

20

Step-by-step explanation:

$V_{right\: square \: pyramid} = \frac{1}{3} {a}^{2} h \\ \\ \therefore \: 1500 = \frac{1}{3} {(15)}^{2} (x)\\ \\ \therefore \: 1500 = \frac{1}{\cancel 3} \times \cancel {225} (x) \\ \\ \therefore \: 1500 = 75x \\ \\ \therefore \: x = \frac{1500}{75} \\ \\ \therefore \: x = 20$

6-√8 divide √2-1

agasfer [191]

Answer:

4 $\sqrt{2}$ +2

Step-by-step explanation:

$\frac{6-\sqrt{8}}{\sqrt{2}-1}$

= $\frac{6-\sqrt{8}}{\sqrt{2}-1}$ × $\frac{\sqrt{2}+1}{\sqrt{2}+1}$

= $\frac{(6-\sqrt{8})(\sqrt{2}+1)}{2-1}$

=6 $\sqrt{2}$ + 6 - $\sqrt{8}\sqrt{2}$ - $\sqrt{8}$

=6 $\sqrt{2}$ + 6 - 4 - $\sqrt{8}$

=6 $\sqrt{2}$ + 2 - $\sqrt{8}$

=6 $\sqrt{2}$ + 2 - 2

=4 $\sqrt{2}$ +2

for $\sqrt{8}$ = 2 $\sqrt{2}$ ,

$\sqrt{8}$ = $\sqrt{2*2*2}$

= ( $\sqrt{2}$ )^2 × $\sqrt{2}$

=2 × $\sqrt{2}$

How to write y-2=-1/3 (x+6) in standard form and why PLZ HELP

stich3 [128]

$y-2=-\frac{1}{3}(x+6)\\y=-\frac{1}{3}(x+6)+2$

Simply move -2 to another side.

$y=-\frac{x}{3}-2+2$

Distribute -1/3 in (x+6)

$y=-\frac{x}{3}$ ---> Answer
