Answer:

x = 21

Step-by-step explanation:

You need to understand the concept of linear angles and supplementary angles.

The square in the K*J angle is a 90 degree symbol, and if you add the 15 degrees making up that K*N angle, it makes 105 degs.

Since the lines KL and MN are intersecting, they are adjacent, so the angle K*M and N*L are equivalent, and K*N and M*L are equivalent.

This means that M*L is also 105 degs.

If 105 degs is equal to 5x, you can simply divide to find the unit rate of x.

105/5

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.

The opooste angles are equal

so
4y-8=79+y
minus y both sides
3y-8=79
add 8 both sides
3y=87
diide both sides by 3
y=29
