The roots of the quadratic equation ax^2+bx+c=0 are

x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}.

Here the given quadratic equation is 5x^2-13x+7=0. Here a=5,b=-13,c=7.

The roots are

x=\frac{13 \pm \sqrt{13^2-4*5*7}}{2*5} \\ x=\frac{13 \pm \sqrt{29}}{10}

Toretto has 7 cars and Brian has 3 cars. Rome has p more than the product of Toretto and Brian's cars. Write an expression for t
Minchanka [31]
Answer:

(7 x 3) + p

Explanations:

The number of cars Toretto has = 7

The number of cars Brian has = 3

The product of Toretto and Brian Cars = 7 x 3

The product of Toretto and Brian Cars = 21

Rome has p cars more than the product of Toretto and Brian's cars

The expression for the number of cars Rome has will be:

Number of Rome's cars = (7 x 3) + p

which can also be simplified as 21 + p

Solve 3(x - 2) &lt; 18. A{x\x&lt;8)<br> B{x1x &gt; 8)<br> C[xlx&lt;-8}<br> D{xl x&gt;-8)
Evgen [1.6K]

Answer:

A. {x | x < 8}

Step-by-step explanation:

First, we divide both sides by 3.

3(x - 2)/3 < 18/3

Then simplify.

x - 2 < 6

Lastly, add 2 to both sides.

x - 2 + 2 < 6 + 2

<u>x < 8</u>
