Answer:

2<em>n</em>+10

Step-by-step explanation:

you just distribute the -2 and you get -14+2<em>n</em>+4 and then add and you'll get 2<em>n</em>+10

if you are solving for the variable <em>n </em>then you would want your equation like this 2<em>n</em>+10=0

next you would put the 10 on the other side of the equation and have 2n=-10

finally you would divide by 2 and get n=-5

Ivanshal [37]

Answer:

plz mark brainliest..

Step-by-step explanation:

AC is the hypotenuse = 10

AB is side opposite to <C

<C = 30°, <B = 90°

side opposite to 30° is equal to half of hypotenuse

therefore,

AB = 1/2 × AC

AB = 1/2 × 10

AB = 5

therefore number 5 is answer

hope it will help you
