2x+4x=180(linear pair)
->x=30
A) growth; B) decay; C) growth; D) decay
A is growth because the value of b raised to the exponent is larger than 1.
B is decay because the value of b raised to the exponent is smaller than 1.
C is growth because the value of b raised to the exponent is larger than 1.
D is decay because the value of b raised to the exponent is smaller than 1.
There is a video on khanacademy, search "rationalize the denominator." Then instead of getting the answer you will learn how to do it and be able to do it on other problems in the future.
15 * 2 / 6 * 18- 5 + 70 - 18 + 23 =
30/6 * 18 - 5 + 70 - 18 + 23 =
5 * 18 - 23 + 93 =
90 - 23 + 93 =
183 - 23 =
160 <==
