Answer:C
Step-by-step explanation:
x=4+√21,4−√21
Decimal Form:
8.58257569
0.58257569
Assume L=1.5W, where W=width, L= Length of the triangle.
Therefore,
Perimeter (P) = 2(W+L) = 2(W+1.5W) = 2(2.5W) = 5W=20 => W=20/5 = 4 in
Then, L=1.5W = 1.5*4 = 6 in
Area, A= L*W = 6*4 = 24 in^2
The answer c, because they got 9 out of 15 flips being heads. This probability is 0.6. The other answers are not accurate.
