Answer: use search website
Step-by-step explanation: its good
Hey, there!
The parentheses would make it multiplication
The word sum means add
A number was unknown, so we will label it as "x"
So, let's see what we're working with here!
If you chose "Option A" the question would be "five multiplied by a number and the sum of 3" (that doesn't give you the right answer"
For B. same thing with option A
For "Option C" its not asking you "a number with sum of three times five"
So, this leaves "Option D." as your answer because 3 is getting multiplied by the sum of some number and five
Good luck on your assignment and enjoy your day!

There are 2 significant figures (sig figs) which are the two '5' digits. The zeros aren't considered sig figs because we can write the number as 5.5 * 10^8 to represent the exact same idea. The 0's are simply placeholders to tell how big the number is, not necessarily how accurate it is. If the 0s were between the decimal point and a nonzero value, then the 0s would be significant. If the 0s were to the right of the decimal, then they would be significant.
