(22) If x² = 225, then x =
(24) If x= 343, then x =

Hi there!

Your answers are:

22) x= 15

24) **REFER BELOW**

Step-by-step explanation:

22)

x^2 = 225

Find the square root of both sides!

√x^2 = x

√225 = 15

x= 15

24)

X= 343

If unaltered x is equal to 343, then x itself is equal to 343

If you accidentally made a typo and meant to say x^2 = 343;

x^2 = 343

find the square root of both sides!

√x^2 = x

√ 343 = 7√7 or roughly 18.52

Hope this helps!

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)
