Answer:
3. 2x+18=4x+26
Step-by-step explanation:

3 because 3•3 is 9 and 9•3 is 27
Step-by-step explanation:
You have to do first and second derivatives :
y = a sin 3x + b cos 3x
dy/dx = 3a cos 3x - 3b sin 3x
d²y/dx² = - 9a sin 3x - 9b cos 3x
Next, you have to compare it :
let d²y/dx² = ky,
-9a sin 3x - 9b cos 3x = k(a sin 3x + b cos 3x)
-9(a sin 3x + b cos 3x) = k(a sin 3x + b cos 3x)
Therefore, k is equals to 9.
Answer:
The answer is 17 and no
Step-by-step explanation:
#11 The room is a cube so...
cube root the volume 4913
³√4913=17
The length of the room is 17 feet.
#12
Square root 121
√121=11
Since the car is 13 feet the car will not fit in the garage which is 11ft.
