Find the distance between (2, -75) and (10,235).
zmey [24]

Answer:

310.1

Step-by-step explanation:

Use the distance formula:

\sqrt{(10-2)^2+(235-(-75))^2}

Simplify inside the parentheses

\sqrt{(8)^2+(310)^2}

Simplify exponents

\sqrt{64+96,100}

Simplify by adding

\sqrt{96,164}

Simplify

\sqrt{96,164} =310.1

Given the figure below, find the values of x and z.<br> (8x – 20)<br> (14x – 20)
Gnesinka [82]

Answer:

Problem #1:  x = 2.5

Problem #2:  x = 10/7

Step-by-step explanation:

Step 1:  Find the value of x in (8x - 20)

8x - 20 = 0

<u>Add 20 to both sides</u>

8x - 20 + 20 = 0 + 20

<em>8x = 20</em>

<em />

<u>Divide both sides by 8</u>

8x / 8 = 20 / 8

<em>x = 2.5</em>

<em />

Answer:  x = 2.5

<em />

Step 2:  Find the value of x in (14x - 20)

14x - 20 = 0

<u>Add 20 to both sides</u>

14x - 20 + 20 = 0 + 20

<em>14x = 20</em>

<em />

<u>Divide both sides by 14</u>

14x / 14 = 20 / 14

<em>x = 10/7</em>

<em />

Answer:  x = 10/7
