5 15
Step-by-step explanation:
Here is the correct and complete question:
The total number of hours, t, that Trent has practiced his guitar after d days is modeled by the equation t = 3d.
Complete the table below.
d t
1
3
15
Step-by-step explanation:
For the first space, we are to determine the value of t when d is 1
From the given equation, t = 3d, put d = 1 and determine t
t = 3d
∴ t = 3(1) = 3×1
t = 3
For the second space , we are to determine the value of t when d is 3
Put d = 3 in the equation to determine t
t = 3d
∴ t= 3(3) = 3×3
t = 9
For the third space, we are to determine the value of d when t is 15.
Put t = 15 in the equation and then find d
t = 3d
∴ 15 = 3d
Divide both sides by 3
15/3 = 3d/3
5 = d
∴ d = 5
The distance is 1410 miles.
The triangle above shows how speed, distance and time are related. D = s x t
S= d/t
T=d/s

Answer:
Step-by-step explanation:
I think the one you want is the last one, but I've never called it that.
21x^2 + 147x + x^3 + 343
x^3 + 343 is a cubic binomial. It factors into (x + 7) (x^2 - 7x + 49)
21x(x + 7) + (x + 7)(x^2 - 7x + 49)
(x + 7) [ 21x - 7x + x^2 + 49)
(x + 7) [x^2 + 14x + 49]
(x + 7) ( x+7)^2
(x + 7)^3
It's the only answer that does factor. There must be a simpler way of doing it, but this will give you the right answer.
