12.0/8=15. If you at .0 to a # the amount is the same just in a different way.
2 equal angles is the correct answer
You use FOIL
First
Outer
Inner
Last
(-x - 4)(x + 4)
The first terms for both are -x and x
-x * x = -x^2
Outer are -x and 4
-x * 4 = -4x
Inner are -4 and x
-4 * x = -4x
Last are -4 and 4
-4 * 4 = -16
Combine:
-x^2 - 4x - 4x - 16
-x^2 - 8x - 16
Answer:
For any value of x
Step-by-step explanation:
Solve by using system of equations!
3x+12
3(x+4)=3x+12
3x+12=3x+12
x=x
This means that any value of x would create the same answer for both equations.
Answer:
At 4:48 p.m.
Step-by-step explanation:
angle between hands of the clock is given by
θ= | 30H- 11/2M |
Where H and M are hours and minutes respectively.
H=4
θ= | 30×4- 11/2M |
⇒144°= | 120- 11/2M |
solving Above equation we get M= 48 minutes
Time = 4:48 p.m.
therefore between 4 and 5 p.m. at 4:48 p.m. the angle between minute and hour hand is 144°
