Step-by-step explanation:
b+/-(√b^2-4ac)/2a
7+/-(√7^2-4(2)(3)/2(2)
=-3 or =-1/2
3.12 (repeating) = 3 12/99 reduces to 3 4/33 or 103/33
if there is one number repeating, like 0.222...u put that one number over 9...making it 2/9.
if there is 2 numbers repeating, like 0.1313...u put the two repeating numbers over 99...making it 13/99
if there are 3 numbers repeating, like 0.123123...u put ur three repeating numbers over 999...making it 123/999
Each coin will either land as a head or a tail. - 2 possible results.
for 5 coins its 2*2*2*2*2 = 32 different results.
Answer:
Find area of parallelogram:
Area of Parrallelogram = Base x Height
A = 14 x 6
A = 84 (units^2)
Area of circle:
Area =



Both semi-circles make a circle so:
Total Area = Parrallelogram + Circle
Total Area = 84 + 201.1
Total Area = 285.1 units^2
