Help me please quick 9 + 12n

answer is 0

n= -0.75

plug it in multiply it by 12

which is -9

-9+9=0

Step-by-step explanation:

n = -0.75

Step-by-step explanation:

Simplifying

9 + 12n = 0

Solving

9 + 12n = 0

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-9' to each side of the equation.

9 + -9 + 12n = 0 + -9

Combine like terms: 9 + -9 = 0

0 + 12n = 0 + -9

12n = 0 + -9

Combine like terms: 0 + -9 = -9

12n = -9

Divide each side by '12'.

n = -0.75

Simplifying

n = -0.75

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
