By plotting the two points on a graph sheet and joining them gives the line required.

PLEASE HELP ITS URGENT!!!!!!

Delvig [45]

Answer:

LCD-3x(x+2)

Final answer- x2-4x+4/ 3x2+6x

Step-by-step explanation:

okay so LCD is 3*x*(x+2)

= 3x(x+2)

so multiyling the fist expresion by x+2 and the second by x we get

2x+4+ x2-6x/ 3x(x+2)

= so

x2-4x+4/3x(x+2)

x2-4x+4/ 3x2+6x

if my answer helps please mark as brainliest.

Find all the missing elements

Andre45 [30]

Answer:

A = 23°

b = 9.5

c = 14.7

Step-by-step explanation:

B = 32°

C = 125°

a = 7

✔️Find A:

A = 180° - (B + C) (sum of triangle)

A = 180° - (32° + 125°)

A = 23°

✔️Find b using Law of Sines:

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

Plug in the values

$\frac{sin(23)}{7} = \frac{sin(32)}{b}$

Cross multiply

$sin(23)*b = sin(32)*7$

Divide both sides by sin(23)

$b = \frac{sin(32)*7}{sin(23)}$

b = 9.5 (nearest tenth)

✔️Find c using Law of Sines:

$\frac{sin(A)}{a} = \frac{sin(C)}{c}$

Plug in the values

$\frac{sin(23)}{7} = \frac{sin(125)}{c}$

Cross multiply

$sin(23)*c = sin(125)*7$

Divide both sides by sin(23)

$c = \frac{sin(125)*7}{sin(23)}$

c = 14.7 (nearest tenth)
