Answer:

  x = 3

Step-by-step explanation:

It is convenient to remember the ratios of side lengths of these "special triangles."

The side ratios of ΔABC are 1 : 1 : √2, so BC = AC/√2 = 6.

The side ratios of ΔBCD are 1 : √3 : 2, so BD = BC/2 = 6/2 = 3.

The value of x is 3.

Write the following quadratic expression in standard form: ( 2 x − 1 ) ( 3 x − 1 )
jeka94

Answer:

<em>6</em>x^{2}<em> - 5</em>x<em> + 1</em>

Step-by-step explanation:

Standard form is: ax^{2} +bx+x

To reach that you have to distribute:

(2x - 1) (3x - 1)

2x (3x - 1) = 6x^{2} - 2x

-1 (3x - 1) = -3x + 1

Combine like terms:

6x^{2} - 5x + 1

Stan worked 4 years less than Marco.This year Stan has worked 29 years.If b is how long Marco worked, the equation b - 4 = 29 re
MA_775_DIABLO [31]

Answer:

Add 4 on both sides.

In the equation there is a -4.

If -4+4=0, that is how you would get rid of the -4.

But, you need to add 4 to 29 to really get rid of the -4.

So, 29+4 is 33.

b=33
