log₉(<em>x</em> - 7) + log₉(<em>x</em> - 7) = 1
2 log₉(<em>x</em> - 7) = 1
log₉(<em>x</em> - 7) = 1/2
Take the base-9 antilogarithm of both sides; in other words, make both sides powers of 9:
can also be written as √9 = 3, and , so the equation reduces to
<em>x</em> - 7 = 3
Solve for <em>x</em> :
<em>x</em> = 10
Answer:
43.96
Step-by-step explanation:
The radius is 7 inches. This'll mean the diameter is 14, and the circumference of a circle is pi * diameter. This'd be 3.14 * 14 = 43.96 inches :)
