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

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
