Answer:
290.6 cm²
Step-by-step explanation:
2(4 · 12 + 4 · 12 + 4 · 4) = 224
224 + 66.6 = 290.6

Answer:
3
Step-by-step explanation:
x - 9
12 - 9
= 3
The answer is 3.
It depends. Everyone have there own preferences . I myself use the completing square method because I can do it fast. But many of my colleagues use quadratic formula. so there is no such thing as which one is easier.
Solve x2−6x−3=0
x2−6x=3
x2−6x+(−3)2=3+9
(x−3)^2=12
take square root on both sides
x−3=±12
x= 3 ±2√3
Step-by-step explanation:
=> The volume of a triangular pyramid can be found using the formula V = 1/3AH where A = area of the triangle base, and H = height of the pyramid
=> The volume of a cone can be found by V = 1/3(Ab)(H) where Ab is base area and H is the height of the cone
The difference between both is that is it's base. A cone has a polygonal base while a pyramid has a tetragonal base
