-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

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
