Anthony writes the numerical expression 2+10×3-2 and says the expression has a value of 34. is anthony correct? explain your answer

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
