Answer:
54
Step-by-step explanation:
Tn = an²+bn
T2 = a2²+2b
2 = 4a +2b
Multiply all through by 2
4 = 8a +4b
4b = 4-8a
T4 = a4² + 4b
20 = 16a +4b
4b = 20-16a
4-8a = 20-16a
16a -8a = 20-4
8a = 16
a = 16/8 = 2
4b = 4-8a = 4-8(2) = 4-16 = -12
b = -12/4 = -3
T6 = a6² + 6b
T6 = 2(36) + 6(-3) = 72 -18 = 54
Answer: 9 × 6 = 54
Step-by-step explanation:
In the Product Game, we need to multiply the both number of factor markers.
Chris and Katie were playing The Product Game. Their factor markers were on 9 and 2.
Number = 9 × 2 = 18
Chris decided to move the marker from 2 to 6.
Now, one maker is on 9 and other is on 6. So,
Number = 9 × (2 + 4)
Number = 9 × 6 = 54
Therefore, 9 × 6 = 54 is a numerical expression to represent his move.
Answer:
-3 + n = 6n + 22
-1n on both sides
-3=5n+22
-22 on both sides
-25=5n
divided by 5
-5=n
