Find the first three terms of the sequence below. T, = n² – 2n - 3

  -4, -3, 0

Step-by-step explanation:

Use the values 1, 2, 3 for n:

  t1 = 1² -2·1 -3 = 1 -2 -3 = -4

  t2 = 2² -2·2 -3 = 4 -4 -3 = -3

  t3 = 3² -2·3 -3 = 9 -6 -3 = 0

The first three terms are -4, -3, 0.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
