Answer:
f(x) = (x-4)(x+2)
Step-by-step explanation:
f(x) = x^2 – 2x – 8
What 2 numbers multiply to -8 and add to -2
-4*2 = -8
-4+2 = -2
f(x) = (x-4)(x+2)
Answer:
30
Step-by-step explanation:
2/3 = x/18
2*18 = 3x
36 = 3x
x=12
so there are 12 boys
12+18=30
Answer:
the distance of the rope between boat and dock is 30
Step-by-step explanation:
to get the distance between the rope and the dock we use tan 40 because we have the opposite as 25.17ft
tan 40 = opposite/adjacent
0.839 = 25.17/a
cross multiply
0.839a= 25.17
a = 25.17/0.839 = 30 ft
The answer is -6. hope this helps
