Nick is solving the equation 3x2=20−7x with the quadratic formula.
which values could he use for a, b, and c?
a = 3, b = −7 , c = 20
a = 3, b = 7, c = −20
a = 3, b = −20 , c = 7
a = 3, b = 20, c = −7

Second option.

Step-by-step explanation:

Given a Quadratic equation in the form:

It can be solve with the Quadratic formula. This is:

In this case, given the Quadratic equation:

You can rewrite it in the form :

- Subtract 20 from both sides of the equation:

- Add to both sides of the equation:

Therefore, you can identify that:

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
