Answer:
Step-by-step explanation:
ASSUMING the given dimensions are the lengths of the legs
we have an equilateral triangle with base 4 and height
h = √(3² - (4/2)²) = √5
A = ½bh = ½(4)(√5) = 2√5 cm²
2x squared +1 - 7x squared +3
72 unit cubes thats the answer
Answer:
424 cm²
Step-by-step explanation:
8 x 11 = 88 = 1 side
88 x 2 = 196 = 2 sides
11 x 6 =66 = 3 sides
66 x 2 = 132 = 4 sides
8 x 6 = 48 = 5 sides
48 x 2 = 96 = 6 sides
196 + 132+ 96 = 424
In every side of the coin, there is a fifty fifty chance
of landing on the other side, so there is a probability of 0.50. In a deck of
cards, there are 52 cards with 26 clubs and another 26 for spades. So in every
random choice, there is a 1/26 probability of the card being chosen.
