Einstein went on to present his findings mathematically: energy (E) equals mass (m) times the speed of light (c) squared (2), or E=mc2. The secret the equation revealed—that mass and energy are different forms of the same thing—had eluded scientists for centuries.
Answer: C
Step-by-step explanation:
is in the third quadrant, so both x and y are negative.
Therefore, the only possible answer is C.
The answer is E. If you draw the quadrilateral out, you can clearly see what it looks like. And you can know from the coordinates that the diagonal of this quadrilateral is not equal. So it can not be rectangle. And also AB//CD and AD//BC.
Answer:
X- 12 months, Y- 450 in total
Step-by-step explanation:
unsure what you would want for the answer to be but,
if plan a were to charge you for a year 20 x 12 would be 240 dollars a year + 10 would be 250 the total cost.
plan b, same thing 15 x 12 is 180 + 20 which would be 200 the total cost.
if you wanted both months added together, it would be 420 since x was 12.
and both sign up fees would be 30 dollars, if they needed a sign up fee for each month as well, it would be 360 per.
the total cost for all of plan a and b together would be 450 because you added the 30 dollar fee to the total of each plan.
