What is the distance between the two points (-8,-6) and (-2,4)?

MAVERICK [17]

Answer:

$\sqrt{136}$ = 11.66 units

Step-by-step explanation:

distance between 2 points (a,b) and (c,d) = $\sqrt{(a^{2}-c^{2} ) +(b^{2}-d^{2} ) }$

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

= $\sqrt{136}$

= 11.66 units

Solve 4(x + 2) = 20

KiRa [710]

Answer:

x = 3

Explanation:

$\sf 4(x + 2) = 20$

$\sf 4x + 8 = 20$

$\sf 4x = 20 - 8$

$\sf 4x = 12$

$\sf x = \frac{12}{4}$

$\sf x = 3$

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3
