It would take 1 1/2 hour to walk three miles.
The smallest root is -5. The other is 3.
You can get these by factoring. The easiest way to do so is by pulling out a 4 first and then using your normal factoring patterns.
Answer:
Once the equation is in standard form, factor the quadratic expression. 2x2 + 7x + 3 = 0 (2x + 1)(x + 3) = 0. Using the Zero Product Property set ...
2x2 + 7x = -3
2x2 + 7x + 3 = 0
Once the equation is in standard form, factor the quadratic expression.
2x2 + 7x + 3 = 0
(2x + 1)(x + 3) = 0
Using the Zero Product Property set each factor equal to 0 and solve for x.
2x + 1 = 0
2x + 1 - 1 = 0 - 1 x + 3 = 0
2x = -1 x + 3 - 3 = 0 - 3
2x 2 = -1 2 x = -3
x = -1 2
The solutions to the equation are -1 2 and -3.
A whole number will be 3 and as a fraction unit fraction it would be 2/8
8 less than a number can be written as
x-8
when you see the word <u>is</u> you should think of = sign
so the equation will be x-8=24
Now solve adding 8 to both sides.
x=24+8
x=32
