It’s a little surprising that this question didn’t come up earlier. Unfortunately, there’s no intuitive way to understand why “the energy of the rest mass of an object is equal to the rest mass times the speed of light squared” (E=MC2). A complete derivation/proof includes a fair chunk of math (in the second half of this post), a decent understanding of relativity, and (most important) experimental verification.
Answer:
(x-4)(x-5)
That is the answer, hope it helps.
Answer:
6x = 42
Step-by-step explanation:
The formula to find the area of a rectangle is 
. Since we have a value for the width, we simply need to find what to multiply to 6 to get 42.
Let x = length
6x = 42
We then divide both sides by 6 to find the value of x.
So we know the length is 7.
To check the answer we substitute x with 7.
