Write the product as a trinomial. (2x + 3)(4x – 2)

Simora [160]

=(2x+3)(4x+−2)

=(2x)(4x)+(2x)(−2)+(3)(4x)+(3)(−2)
=8x2−4x+12x−6
=8x2+8x−6

3x^2-3x ----------- -3 x^2-9x please give me the simplified answer + explanation

STatiana [176]

You want us to simplify $\frac{3x^2-3x}{x^2-9x}-3$

first, factor top and bottom
$3x^2-3x=3x(x-1)$
$x^2-9x=x(x-9)$

so we have
$\frac{3x(x-1)}{x(x-9)}-3=$
$\frac{3(x-1)}{x-9}-3$
we want to combine fractions so multiply 3 by $\frac{x-9}{x-9}$
$\frac{3(x-1)}{x-9}-\frac{3(x-9)}{x-9}=$
$\frac{3(x-1)-3(x-9)}{x-9}=$
$\frac{3x-3-3x+27}{x-9}=$
$\frac{24}{x-9}$

the simplified answer is $\frac{24}{x-9}$

If DC=6x and DA=4x+18, find the value of x then, find AD

shepuryov [24]

The value of x is 9 and AD is 54.

Step-by-step explanation:

From figure, if DC = AD, we can solve for value 'x'

DC = AD

Given:

DC = 6 x

DA = 4 x + 18

Equating the values of both, we get

6 x = 4 x + 18

6 x - 4 x = 18

2 x = 18

x = 9

So, the value of x is 9. By using this value of x, find AD

AD = 4 (9) + 18

AD = 36 + 18

AD = 54
