Alice needs to go to basketball practice. she could ask her brothers sam or alex but it is not guaranteed they will take her. the probability is written on some of the tree diagram branches

i would love   to but there is no graph shown

step-by-step explanation:

i am so sorry

there are no choices to this, can you give us some choices so that i can answer it

step-by-step explanation:

is the anwser b. (-13)?

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
