The answer is E show ur work :)
Answer:
Step-by-step explanation:
The club can clean 1 3/4 miles per day:
rate of work completion =
7 miles
-------------
4 days
Therefore, in four days the club can clean this distance:
7 miles 4 days
-------------- * ----------- = 7 miles (which is equivalent to 21/3 miles)
4 days 1
No, Jacqueline is not correct in stating that the club could clean 19/3 miles.
Answer:
- 24x + 9
Step-by-step explanation:
Differentiate each term using the power rule
( a ) = na
Given
f(x) = - 12x² + 9x, then
f'(x) = (2 × - 12)x + (9 × 1) = - 24x + 9
Let us call them a, b and c
we know that
a+1=b
a+2=c
a+2b=12+c
we can deduce the following:
a+2(a+1)=12+(a+2)
3a+2=a+14
2a=12
a=6
so b would be 7 and c would be 8
Makes sense ?
