2x^2 - 32y^2 ​

2(x^2-16y^2)

Step-by-step explanation:

9514 1404 393

  2(x -4y)(x +4y)

Step-by-step explanation:

Once you factor out the common factor of 2, what remains is the difference of squares. That can be factored further.

The factoring of the difference of squares is ...

  a² -b² = (a -b)(a +b)

Then we have ...

  2x² -32y² = 2(x² -16y²) = 2(x² -(4y)²)

  = 2(x -4y)(x +4y)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
