what is the best and easiest method to use to find sides A and B?
B
Answer:
i think the answer would be 4c + 6m = 100, 8c + 12m = 200
Step-by-step explanation:
A (x,-y). When you reflect over the x-axis, the y becomes negative
Work done on cart
:
W
=
6000
J
Kinetic energy of cart
:

K
=
6000
J
Explanation:
Work done
W
is defined as the product of force
F
and distance
s
:
⇒
W
=
F
⋅
s
Let's substitute the values of
F
and
s
into the equation:
⇒
W
=
300

Answer:
88 Tickets were sold
Step-by-step explanation:
20*$4=$80
$216-$80=$136
