The value of b is -16 and the value of ac is 60 after comparing with the standard equation.

<h3>What is a quadratic equation?</h3>

Any equation of the form \rm ax^2+bx+c=0 where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}

We have a quadratic function:

= 3x² - 16x + 20

On comparing with standard function:

b = -16

a = 3

c = 20

ac = 3(20) = 60

Thus, the value of b is -16 and the value of ac is 60 after comparing with the standard equation.

Find the length of ST. St= 5x+2 and TV = 3x+12 <br> Thank you for anyone who does answer(:
valentina_108 [34]
I think you forgot to include that T is the midpoint of SV, but what this would mean is that ST = TV.
5x + 2 = 3x + 12

Subtract 2 from both sides.
5x = 3x + 10

Subtract 3x from both sides.
2x = 10

Divide both sides by 2.
x = 5

Now plug that x into ST.
ST = 5(5) + 2
ST = 25 + 2
ST = 27
