Answer:
Step-by-step explanation:
Distance walked by Arthur = 5/8 miles
Distance ride by Jonathan = 8 times that of Arthur
it means that Distance rode on bus by Jonathan is 8 multiplied by Distance walked by Arthur
Distance rode on bus by Jonathan = 8 * Distance walked by Arthur
Distance rode on bus by Jonathan = 8 * 5/8 = 5 Miles Answer
The sum of two sides of a triangle must be greater than the third side
1) 5+9>14
14>14 It is incorrect so you can’t have these lengths
2)7+7>15
14>15 X
3)1+2>4
3>4 X
4)3+6>8
9>8
6+8>3
14>3
8+3>6
11>6
So the fourth choice is correct
Let's make a table of differences
0 3 8 15 24
3 5 7 9
2 2 2
Constant second difference means a quadratic polynomial,
f(n)=an² + bn +c
f(1)=0, f(2)=3, f(3)=8
0 = a+b+c
3 = 4a + 2b + c
8 = 9a + 3b + c
Subtracting pairs
3 = 3a+b
5 = 5a + b
Subtracting,
2 = 2a
a = 1
b = 5 - 5a = 0
c = -a-b = -1
f(n)=n² -1
Duh, shoulda noticed that at the beginning.
f(17)=17²-1 = 288
a₁ =5
aₙ = aₙ₋₁ - 7
aₙ = a₁ + d(n-1)
aₙ = 5 - 7(n-1)
a₇ = 5 - 7(6) = -37
Answer: -37
Answer:
C) 3 sets of -2 tiles
Step-by-step explanation:
Its -2 three times, making it -6
