16=22-6
Do the math on paper and you should get it.
Answer:
36√3 + 144
Step-by-step explanation:
Given that,
base of the pyramid is an equilateral triangle with sides = 12
Formula to calculate total surface area of pyramid
<h3>
[Base Area] + 1/2 × Perimeter × [Slant Length]</h3>
Base Area
1/2 (height) (base)
1/2 (√12²-6²)(12)
6(6√3)
36√3
perimeter of base
sum of all sides = 12 + 12+ 12
= 36
slant height = √10²-6²
= 8
put all these values in the formula above
36√3 + 1/2(36)(8)
36√3 + 144
Total area for the pyramid with the equilateral base =
36√3 + 144
Answer: 14y
Step-by-step explanation:
7 times 2 = 14
7 times 5 = 35
14y + 35z - 35z
35 - 35 = 0
You are left with 14y
Commutative Property is used here
I think it is they both have a 1 and a 0 in them.
