Answer:

  • D. A = x² + 44x = 808

Step-by-step explanation:

Check if the relationship is linear. Verify the difference between areas.

We can see the difference is not common.

It means we can exclude options B and C.

The remaining options are quadratic (A and D).

<u>Try the last column with option A:</u>

  • 4813 = 45² + 1908
  • 4813 = 3933
  • False

<u>Verify the last option:</u>

  • 4813 = 45² + 44*45 + 808
  • 4813 = 4813
  • Correct

We can check and confirm the other columns are correct as well.

Factorize fully 12x^3-4x^2
serg [7]

Answer:

4x² (3x - 1)

Step-by-step explanation:

→ Find the LCM of 12 and 4

LCM = 4

→ Find the LCM of x³ and x²

LCM = x²

→ Combine both LCM's together to form the outside multiplier

4x² (? - ?)

→ Complete the operations of 12x³ ÷ 4x² to find the first ? and 4x² ÷ 4x² to find the second ?

12x³ ÷ 4x² = 3x

4x² ÷ 4x² = 1

→ Therefore,

∴ 4x² (3x - 1)
