Answer:
Step-by-step explanation:
2
The coefficient is the number in front of the variable.
So, in this case, the coefficient of n^2 is 6 and of n is 2.
During a week:
Kevin works 3z during 5 days
kevin work (4z-7) during 1 day.
Kevin work 0 during 1 day.
z=unit time
f(z)= number of hours kevin works in one week.
f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7
The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
<span>(-4x^2)^3
= (-4)^3 x^6
= - 64x^6</span>
Answer:
Step-by-step explanation:
To solve by factoring, complete the square by dividing 8 from 8x in 2. Then square the result 4 to get 16. Add 16 to both sides.
The equation is now factored. To solve, take the square root of both sides and solve for x.
Alright, do you know what mean is?
