Which board geometrically represents 4x2 – 1 using algebra tiles? An algebra tile configuration showing only the product spot, w
NemiM [27]

An algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

The correct option is B.

Given

Equation; \rm 4x^2 - 1

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero.

Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

4x² -1 = 0 is a quadratic equation.

An algebra tile configuration showing only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

Then,

The factors of the polynomial is;

\rm 4x^2 - 1=0\\\\ 4x^2-2x+2x-1=0\\\\ 2x(2x-1)+1(2x-1)=0\\\\(2x-1)(2x+1)=0

Hence, an algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

More about the quadratic equation link is given below.

Answer:

9a^3b^3.

Step-by-step explanation:

The GCF of 9 and 27 is 9.

For a^4 and a^3 it is a^3.

For b^4 and b^3 it is b^3.

Answer is therefore:

9a^3b^3.

Estimate then record the product $473x9
ladessa [460]
So because 9 and 10 are close to each other, and the fact that 10 is really easy to multiply by, you do 473 x 10 which is 4730, because you just add a 0 to the end. 
This means that an estimate is 4730 or if you want to be less specific, <4730, because 9 is less than 10. 
The actual product though is 4257.
