-8(-4+n)<-40 help me pls

n > 1

Step-by-step explanation:

To solve this inequality, we need to get the variable "n" alone. Follow PEMDAS to do so :

Parenthesis

Exponent

Multiplication

Division

Addition

Subtraction

We can first distribute the -8 to -4 and n to get rid of the parenthesis.

((-8)-4 + (-8)n)

-32 + -8n < -40

Now add 32 to both sides.

-40 + 32 = -8

-8n < -8

Now divide -8 by both sides, don't forget to switch the inequality sign since you're dividing by a negative number.

n > 1

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

391.6 is the correct answer
