Do you mind taking a clearer picture of the graph? I can’t answer without it.
Answer:
x = 3.75 cm
Step-by-step explanation:
If we assume ΔABC ~ ΔXYZ, then ...
YZ/BC = YX/BA . . . . . . corresponding sides are proportional
x/15 = 3/12 . . . . . . . . . . . fill in given values
x = 15(3/12) = 15/4 . . . . . multiply by 15
x = 3.75 . . . cm
Answer:
(0,-5/2,-1)
Step-by-step explanation:
x(2x+5)(×+1)=0
x=0 2x+5=0 x+1=0
2x=-5 x=-1
x=-5/2
