Step-by-step explanation:

\underline{ \underline{ \text{Given \: points}}} :

  • C ( 3 , -2 ) & D ( 7 , -8 )

Let the point C ( 3 , -2 ) be ( x₁ , y₁ ) & the point D ( 7 , -8 ) be ( x₂ , y₂ ) .

\underline{  \underline{ \text{To \: find}}} :

  • Length of CD

\underline{ \underline{  \text{Solution}}} :

\boxed{ \sf{Distance =  \sqrt{(x_{2} -x_{1} )^{2}  + (y_{2} - y_{1})^{2} }   }}

⇢ \tt{CD =  \sqrt{ {(7 - 3)}^{2}  +  {( - 8 - ( - 2))}^{2} } }

⇢ \tt{CD =  \sqrt{ {(4)}^{2} +  {( - 8 + 2)}^{2}  } }

⇢ \tt{CD =  \sqrt{16 +  {( - 6)}^{2} } }

⇢ \tt{CD =  \sqrt{16 + 36}}

⇢ \tt{CD =  \sqrt{52}}

⇢ \tt{CD = 7.2 \: units}

\pink{   \boxed{\underline{ \underline{ \tt{Our \: final \: answer :  \boxed{ \underline{ \tt{7.2 \:   \text{units}}}}}}}}}

Hope I helped ! ツ

Have a wonderful day / night ! ♡

Gnom [1K]

Answer:

hello : 256 words

Step-by-step explanation:

2 minutes and 30 = (2×60)+30=150seconds

4 minutes = 4 ×60 = 240 seconds

 150seconds  →160 words

240 seconds → x ?

x = (160×240) / 150 = 38400/150= 256 words

-4k + 2(5k − 6) = −3k – 48
nalin [4]

Answer:

k = -4

Step-by-step explanation:

-4k + 2(5k − 6) = −3k – 48

Distribute on the left side.

-4k + 10k - 12 = -3k - 48

Combine like terms on the left side.

6k - 12 = -3k - 48

Add 3k to both sides.

9k - 12 = -48

Add 12 to both sides.

9k = -36

Divide both sides by 9.

k = -4
