Sub x=3 into ((x^2)-x)^2 - (x^2 - x) = 30. So the answer is A.
Answer:
it is 40!
Step-by-step explanation:
well since area is l x w 13+10=23
and 12+5= 17
A. F(x)= 3x+6 =12
3x = 12-6
3x = 6
x=2
B. x=10, f(x)= 3*10+6 = 30+6 = 36
C. f(x) = 3x+6 = 6
3x = 6-6
3x=0
x=0
D. x=5, f(x) = 3x+6 = 3*5+6 = 15+6 = 21
We are given total 10 tree seedlings.
Number of workshops = 2.
Here order doesn't matters.
<em>When order doesn't matters we apply combination.</em>
We know formula of combination:

For the given situation, we have
n=10 and r=2.
Plugging values in formula, we get


<h3>Therefore, 45 different ways can the nursery give out seedlings.</h3>
