[ 6 . 2 + 2 - [ - 6]] [ - 5 + | [- 18 ÷ 6 ] | ]
i need some help

-28.4

Step-by-step explanation:

Remove parentheses:

(6.2+2+6)(-5+| -18÷6| )

Simplify 6.2 +2 to 8.2

(8.2+2+6)(-5+| -18÷6|)

Simplify  8.2+6 to 14.2

14.2(−5+∣−18÷6| )

Divide −18÷6= -3

14.2(−5+∣−3∣)

Simplify ∣−3∣

you get: 14.2 x (-5+3)

Remove parentheses and simplify -5+3= -2 to get:

14.2 x -2

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
