Answer:
1/3
Step-by-step explanation:
Turned 20 minutes, so the minute hand turned 20 times per hour
There are 60 minutes in 1 hour, so the minute hand turns 60 times per hour
Therefore, the fraction is 20/60, simplified to 1/3
1. Divide by 4
sqrt 2x+8 = 6
2. Square both sides to remove square root
2x+8 = 36
3. Subtract 8
2x = 28
4. Divide by 2 to make x by itself
x = 14

Answer:
-3x^2 - 21x
Step-by-step explanation:
This question is representing multiplying two functions :
We are finding f(x) * g(x)
We know that f(x) is -3x and g(x) is x + 7, therefore :
(-3x)(x + 7)
Follow FOIL :
First :
(-3x)(x)
-3x^2
Outer :
(-3x)(7)
-21x
Therefore the answer is :
-3x^2 - 21x
