Write the equation you would use to find x, then solve for x.
goldfiish [28.3K]

Answer:

x + 6x+10   + x+2 = 180

x = 21

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

x + 6x+10   + x+2 = 180

Combine like terms

8x + 12 = 180

Subtract 12 from each side

8x+12-12 = 180-12

8x =168

Divide each side by 8

8x/8 = 168/8

x =21

Answer:

3rd option

Step-by-step explanation:

(\frac{f}{g} )(x)

= \frac{f(x)}{g(x)}

= \frac{2x^2-5x-3}{2x^2+5x+2} ← factorise numerator and denominator

= \frac{(x-3)(2x+1)}{(x+2)(2x+1)} ← cancel (2x + 1) on numerator/ denominator

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

Which of the following are one-dimensional and have infinite length?
Alona [7]
Out of the choices, the entities with only one dimension and have infinite length are the line and ray. The line extends to both sides while the ray is restricted by an endpoint on one side but can extend infinitely to the other side. The answers are therefore letter D and F.
