Answer:

  • x - 4

Step-by-step explanation:

  • V(x) = x³ - 8x² + 19x - 12

<u>The two of the dimensions given</u>

  • (x - 1) and (x - 3)

<u>and the third one is</u>

  • x + a

<u>Multiply the three dimensions to get the volume:</u>

  • (x - 1)(x - 3)(x + a) =
  • (x² - 4x + 3)(x + a) =
  • x³ - 4x² + 3x + ax² - 4ax + 3a =
  • x³ - (4 - a)x² + (3 - 4a)x + 3a

Comparing with the given function, we get a = - 4

<u>So the missing dimension is:</u>

question is ,four children saved £29 to go on a coach. They each saved the same amount. How much did each saved
Andreas93 [3]
If they saved £29 all together, and if each of them saved the same amount,
then each saved £29/4 = £7.25 or £7 and 25p.

(Before decimalization in 1971, £7.25 would have been £7 and 5s .)
