The ordered expression from the least to greatest number is 62.95, 63.37,63.7
Answer:
Divide both sides by 3.
(x+2)^2=16
Square root both sides.
x+2= ± 4 (plus OR minus, can be either so we have to include both)
Minus 2 from both sides.
x=-2 ± 4
Add and minus the 4 to -2.
x = -2-4 = -6 and x=-2+4 = 2
Yes because 4x3^x =12^x since the coefficient is added to the answer because it is in the 3.
