In multiplication, the order doesn't matter.
2 rows of 7 and 7 rows of 2 is the same.
If you have seven 2's, that's the same as two 7's.
See here:
2 + 2 + 2 + 2 + 2 + 2 + 2 = 14
7 + 7 = 14
Or:
2 * 7 = 7 * 2 = 14
it cant be a negative number or zero
so now you are left with 0.5, 2 and 7.9
15.7 - 0.5 = 15.2 ( 15.2/2 = 7.6) this is possible
15.7 - 2 = 13.7 ( 13.7/2 = 6.85) this is possible
15.7 - 7.9 = 7.8 ( 7.8/2 = 3.9) (7.9/2 = 3.95) since the sides would be shorter than half the base this is not possible to form a triangle
so b can be either 0.5 or 2

Answer:
d = 19 mi
Step-by-step explanation:
Total dist = bike dist + train dist
d = 12(.5) + 20(.5)
d = 6 + 13
d = 19 mi
20 should be the answer because 205 divided by 10 =20
Answer:
f(x) = (8/3)x(x - 1).
Step-by-step explanation:
The vertex form of the function is
y = a(x - 1/2)^2 - 2/3 where a is some constant.
Now the roots are 0 and 1 so
For x = 0
0 = a(-1/2)^2 - 2/3
1/4 a = 2/3
a = 2/3 / 1/4 = 8/3.
So the function is
f(x) = (8/3)(x - 1/2)^2 - 2/3.
3 f(x) = 8(x - 1/2)^2 - 2
= 8(x^2 - x + 1/4) - 2
= 8x^2 - 8x + 2 - 2
3 f(x) = 8x(x - 1)
f(x) = (8/3)x(x - 1).
