What is the value of x please help me

Tju [1.3M]

Answer:

Step-by-step explanation:

ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:

$\dfrac{LM}{PM}=\dfrac{NM}{QM}$

We have:

LM = 3 + 9 = 12

PM = 9

NM = x + 12

QM = 12

Substitute:

$\dfrac{12}{9}=\dfrac{x+12}{12}$ <em>cross multiply</em>

$9(x+12)=(12)(12)$

$9(x+12)=144$ <em>divide both sides by 9</em>

$\dfrac{9(x+12)}{9}=\dfrac{144}{9}$

$x+12=16$ <em>subtract 12 from both sides</em>

$x=4$

What is the sum of 2 / 3x^2 +12x and 8 / c. Need steps

Marta_Voda [28]

Answer:

$\frac{2c}{3x^2c}+ \frac{36x^3c}{3x^2c} +\frac{24x^2}{3x^2c} [\tex]Step-by-step explanation:We need to find sum of 2 / 3x^2 +12x and 8 / cSo, solving:[tex](\frac{2}{3x^2} + 12 x ) +\frac{8}{c}$

Taking LCM of 3x^2 and 1 i.e. 3x^2

$=(\frac{2 + 12 x(3x^2)}{3x^2} ) +\frac{8}{c}\\=(\frac{2 + 36x^3}{3x^2} ) +\frac{8}{c}\\=\frac{2 + 36x^3}{3x^2} +\frac{8}{c}\\LCM \,\, 36x^2 c\\=\frac{(2 + 36x^3)c + 8(3x^2)}{3x^2c}\\=\frac{2c + 36x^3c + 24x^2}{3x^2c}\\= \frac{2c}{3x^2c}+ \frac{36x^3c}{3x^2c} +\frac{24x^2}{3x^2c}$
