Using the quadratic formula to solve 2x2 = 4x – 7, what are the values of x?

Option C is correct.

Step-by-step explanation:

Given Quadratic Equation, 2x² = 4x - 7

We have to find value of x using quadratic formula.

Consider,

2x² = 4x - 7

2x² - 4x + 7 = 0

using Quadratic Formula

we get,

Therefore, Option C is correct.

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'.
