Could somebody please help me find the answers for 'x' for these pictures?

Answer:

Pic 1: $x=31$

Pic 2: $x=20$

Step-by-step explanation:

Picture 1:

$2x+x-3=90\\3x-3=90\\3x=93\\x=31$

First, add the 2x and x together for 3x

Then add 3 to both sides of the equation

Finally, divide each side by 3.

Picture 2:

$7x+x+20=180\\8x+20=180\\8x=160\\x=20$

First, add 7x and x together for 8x

Then, minus 20 from both sides of the equation

Finally, divide each side by 8.

Find the distance of the line segment joining the two points (-4 /2 - /12) and (/32, 2/3)

astraxan [27]

Answer: $4\sqrt{3}$ .

Step-by-step explanation:

Distance formula : Distance between points (a,b) and (c,d) is given by :-

$D=\sqrt{(d-b)^2+(b-a)^2}$

Distance between points $(-4\sqrt{2},\sqrt{12}) \text{ and }(-\sqrt{32}, 2\sqrt{3})$ .

$D=\sqrt{(2\sqrt{3}-(-\sqrt{12}))^2+(-\sqrt{32}-(-4\sqrt{2}))}\\\\=\sqrt{(2\sqrt{3}+\sqrt{2\times2\times3})^2+(-\sqrt{4\times4\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}-\sqrt{2^2\times3})^2+(-\sqrt{4^2\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}+2\sqrt{3})^2+(-4\sqrt{2}+4\sqrt{2})^2}\\\\=\sqrt{(4\sqrt{3})^2+0}\\\\=4\sqrt{3}\text{ units}$

Hence, the correct option is $4\sqrt{3}$ .
