Calculate the length of AB if A is the point (2,3) and B is the point (-2,0)

d1i1m1o1n [39]

Answer:

Formular for coordinate length:

$length = \sqrt{ {(x_{1} - x _{2} )}^{2} + {(y_{1} - y_{2})}^{2} }$

In considerance of coordinates given of A and B

$x _{1} \: \: is \: \: 2 \\ x_{2} \: \: is \: \: - 2 \\ y_{1} \: \: is \: \: 3 \\ y_{2} \: \: is \: \: 0$

therefore substitute:

$length = \sqrt{ { \{2 - ( - 2) \}}^{2} + {(3 - 0)}^{2} } \\ \\ = \sqrt{ {(2 + 2)}^{2} + {3}^{2} } \\ = \sqrt{ {4}^{2} + {3}^{2} } \\ = \sqrt{16 + 9} \\ = \sqrt{25} \\ \\ { \boxed{ \boxed{length \: \: is \: \: 5 \: units}}}$

PLEASE HELP ME W/ MATH ASAP!!

Use similarity property:

14 / (14+6) = 21 / (21 + (x+4))

14/20 = 21/(x+25) cross multiplication property

14*(x+25) = 20*21

14x + 350 = 420

14x = 70

x = 70/14 = 5.
