Answer:
Volume of box = (15−2x)(22−2x)x
C is correct.
Step-by-step explanation:
A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.
The dimension of the cardboard must be 15 x 22 because all options has same value.
We have rectangle cardboard with 15 x 22. We cut square from each corner of the board with dimension x.
New length of box = 22 - 2x
New Width of box = 15 - 2x
Height of the box = x
Volume of box is equal to volume of cuboid.
Volume of box = LBH
= (15-2x)(22-2x)(x)
Hence, The correct volume of the box is (15-2x)(22-2x)(x)

Answer:
Option B: x > 0
Step-by-step explanation:
Option A is wrong because will be 0. So, the inequality can't be divided by 0.
Option C is wrong because 1 will suffice this inequality.
Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).
Leaving us with only option B, which is the right answer.
