A = L * W
280 = 14 * A
A = 280 / 14
A = 20
A = 2 tens
Big rectangle: A = 280 + (14 * B)
378 =280 + 14B
14B = 378 - 280
14B = 98
B = 7
So length = 2 tens + 7 = 27
Answer
C. 2 tens + 7 = 27
Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n
There are 3 0s from the left side of the numbers and going to the decimal point.
<span>So, we're</span> gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.
Answer:
10
Step-by-step explanation:
you divide 5 and 50
Answer: −5
Step-by-step explanation:
simplify: (−5)
Re-order terms so constants are on the left:
