Find the value of 9 - [4 2 - (3 + 2)].
8
6
-2

-2

Step-by-step explanation:

9 - [4^2 - (3 + 2)]

PEMDAS says parentheses first

Working from inside out

9 - [4^2 - (5)]

9 - [16 - (5)]

9 - [11]

Subtract

-2

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

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)
