. Given that 100^2 = a^2, which expression gives the value of the expression 103 × 108?
a. a^2 + 11a + 24
b. a^2 + 24a + 11
c. a^2 + 24a + 24
d. a^2 + 11a + 11

  1. Do not ping the Moderators, unless someone is breaking the rules.
  2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
  3. Do not ping other members randomly for help.
  4. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  5. Wait patiently for a helper to come along.
  6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

Perfect. Then what can we do to get 103 and 108? (hint: ||addition||)

It would just make it easier.

#

( a + 3 ) ( a + 8 )

#

ahh do we apply (x + a ) ( x + b ) here??

ohh thx

This is actually a common trick used in a lot of mental math calculations.

#

You typically take numbers close to multiples of 10, do some addition properties, and execute whatever you need to do.

amm i've got one more silly question.... .can i? 😭

dire sail
#

Sure. Fire away.

hybrid minnow
