The following equation is being multiplied by the LCD. Complete the multiplication to eliminate the denominators

frosja888 [35]

Answer:

$(x+2)(x-2) -1(3x)=(x-3)(x-2)$

Step-by-step explanation:

x+2/3x - 1/x-2 = x-3/3x

$\frac{x+2}{3x}-\frac{1}{x-2}=\frac{x-3}{3x}$

LCD is (3x)(x-2). so we multiply the whole equation by LCD

$(3x)(x-2)(\frac{x+2}{3x}-\frac{1}{x-2}=\frac{x-3}{3x})$

We multiply each term by LCD

$(3x)(x-2)(\frac{x+2}{3x})-(3x)(x-2)(\frac{1}{x-2})=(3x)(x-2)(\frac{x-3}{3x})$

$(x+2)(x-2) -1(3x)=(x-3)(x-2)$

PLEASE HELP!! Question is below

maria [59]

Answer:

Step-by-step explanation:

Complementary means that the angles have a sum of 90° so we can write:

m∠A + m∠B = 90° → 3x + 2 + 8x = 90

11x + 2 = 90

11x = 88

x = 8 which means that m∠B = 8x = 8 * 8 = 64°.

Supplementary means that the angles have a sum of 180° so m∠C = 180° - m∠B = 180° - 64° = 116°.

8. Determine whether the triangles are similar. If so, write a similarity

AlekseyPX

Answer:

Option (4)

Step-by-step explanation:

If ΔLMN is similar to ΔQRS,

Their corresponding sides will be proportional.

$\frac{LM}{QR}= \frac{MN}{RS}= \frac{LN}{QS}$

$\frac{5}{6}= \frac{3}{4}= \frac{6}{7}$

But it's not true.

Therefore, the given triangles ΔLMN and ΔQRS are not similar.

Option (4) will be the answer.
