Answer:
i think it's c but I'm rly not sure on this one...
Alright first ranks doesn’t mean they’ll get it right. It just means how active the user is.
Now to answer your problem, c is given to be 0.5.
So 5(0.5) is the same as 5/2, which is 2.5.
So 10-2.5=7.5
It has to be all of the above
Answer:
105 = (w+8) *w
w = 7 cm
l = 15 cm
Step-by-step explanation:
Area of a rectangle is
A = l*w
l = w+8
105 = (w+8) *w
Distribute
105 = w^2 +8w
Subtract 105 from each side
105-105 = w^2 +8w -105
0 =w^2 +8w -105
Factor
What 2 number multiply to 105 and add to 8
15*-7 = -105
15-7 = 8
(w+15) (w-7) =0
Using the zero product property
w+15 =0 w-7 =0
w=-15 w=7
impossible
not negative
w =7
l = 15
Y= 4 (- x/3 + 1, 2x (-30))
