Answer:

This equation is in vertex form.

Vertex form means that for a quadratic equation, the format is as shown:

y= ±a(b(x-h))²+k. This means that this equation will give you the vertex point directly from the equation.

What is the answer to 56 is 28% of

klio [65]

In mathematics, 'is' would be the equal sign. And 'of' would be the multiplcation sign. The missing number would be any variable.

56 is 28% of a number would be translated algebraically to:

$56 = \frac{28}{100} \times x$

Solving for x, we get:

$56 = \frac{28}{100} \times x$

Divide 28 on both sides

$2 = \frac{x}{100}$

Multiply 100 on both sides

$x = 200$

56 is 28% of 200

Answer:

Step-by-step explanation:

(x²-6x-3)(7x²-4x+7)= ?

Multiply each term of 2nd bracket with the 1st bracket:

=7x²(x²-6x-3) -4x(x²-6x-3) +7(x²-6x-3)

=7x^4-42x^3-21x^2-4x^3+24x^2+12x+7x^2-42x-21

Now solve the like terms:
