Answer:

x - 4

Step-by-step explanation:

V(x) = x³ - 8x² + 19x - 12

The two of the dimensions given

(x - 1) and (x - 3)

and the third one is

x + a

Multiply the three dimensions to get the volume:

(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

So the missing dimension is:

x - 4

3 teachers each bought a box of markers and 2 notebooks. The box of markers cost $2.50. The total was $12.00. Write an equation

larisa [96]

Answer:

$1.12

Step-by-step explanation:

12÷3=4

1 box of markers is $2.50, Multiply $2.50 by 3 and you get $7.50. 12- $7.50= $4.50. $4.50÷ 2= $2.25. $2.25÷2= $1.12

Not 100% but i'm pretty sure this is the answer. Hope this helps. ( if i'm wrong sorry its 2:30 am)
