Answer:
221,000,000,000,000,000,000 = 2.21 x 10^20
therefore, the answer is b
Step-by-step explanation:
Multiply the 2 numbers, 2.5 and 3.9 and then you will get 9.75
Then add the 2 exponents, -15 and 26 and you will get 11
<span>The answer is 9.75 x 10^11</span>
Well we know that it grows 8 in a year. so after 1 year has grown 1 * 8 and after 2 years 2 * 8 and after 3 years 3 * 8 and so on. since x is the year we can say 8x. but it starts with 5 ft so we add in the 5 to get h.
h = 8x + 5
