Which of the following are solutions to the equation 3x2 + 7x + 4 = 0 select all that apply o x=-1 o x=-4/3 x=3/4 x=1

For this case we have the following quadratic equation:

Where:

According to the quadratic formula we have:

Substituting:

We have two roots:

x = -4/3            x=-1

Step-by-step explanation:

3x^2 + 7x + 4 = 0

Factor the equation

(3x+4) (x+1) = 0

Using the zero product property

3x+4 =0         x+1 =0

3x+4-4=0-4    x+1-1=0-1

3x=-4                     x=-1

3x/3 = -4/3

x = -4/3            x=-1

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'.
