Given that:
The amount of radium left after a t years is:
If the quantity left is 10 mg, then:
Changing to logarithm form

Answer:
im pretty sure all you have to do is switch the signs (if its negative it will become positive) but only for the points on the x axis so basically (-12,13) would become (12,13)
Answer:
-6a⁷b⁸
Step-by-step explanation:
(-2a³b²)(3a⁴b⁶)
remove parenthesis:
-2a³b²3a⁴b⁶
reorganize the expression:
-2 × 3a³a⁴b²b⁶
simplify:
-6a⁷b⁸
Answer:
1st equation: 3(12) - 12 = 24
2nd equation: 36 - 12 = 24
