Each of the numbers 10, 70 and 490 is separated from the next by a factor of 7. 10 times 7 is 70; 70 times 7 is 490; 7 times 490 is what? 7 times 7 times 490 is what?
Answer:
12
Step-by-step explanation:
A= (h)(b)/2 = 4×6/2=12

Scientific notation means the numbers have to be between 1 and 10, so here is the answer as well as where to move the decimal
116 if you add 72 plus 43
