choose yes or no to tell whether the expressions are equivalent.

1. 4(5c + 3) and 9c + 7 yes or no

2. 10f – 10 and 2(8f – 5) yes oe no

3. 12g + 21 and 3(4g + 7) yes or no

4. 6(4j – 6) and 24 – 36j yes or no

the solution is 12x-6y

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'.
