Your answer would be the last option, c = √(E/m).
We can see this when we rearrange the equation, as:
E = mc²
÷ m
E/m = c²
√
√(E/m) = c
So you got all the steps in rearranging correct :)
I hope this helps!
Answer:
500+40+3+.2+.08= 543.28
Step-by-step explanation:
3x(x²-5)
Multiply the bracket by 3x
(3x)(x^2)=3x^3
(3x)(-5)=15x
Answer: 3x^3+15x
Sue would have 21 dimes and 12 less of 21 is 9, so sue has 9 nickels
dimes: 21
nickels: 9
3y=2(2+2y); 3y=4+4y; -y=4; y=-4;
