F(x+1) = (x + 1)^3
= 3x + 3
= 3(0) + 3
= 3
I think is 3
Answer: No, he is not correct
The number of combinations is 190
============================================================
Work Shown:
We have 10 shirts, 6 hats, and 4 scarves. This is 10+6+4 = 20 items total.
If we randomly pick out an item, then we have 20 to choose from. After selecting that first item, we have 20-1 = 19 items left to choose from.
So there are 20*19 = 380 different permutations. Order matters with permutations.
Since we aren't worried about order, this means that we've double counted so we have to divide by 2 to fix it.
So there are 380/2 = 190 combinations.
You can use the nCr combination formula
with n = 20 and r = 2 to get the same result.
Answer:
X= 7/5
Step-by-step explanation:
Let's solve your equation step-by-step.
12x−15=6−3x
Step 1: Simplify both sides of the equation.
12x−15=6−3x
12x+−15=6+−3x
12x−15=−3x+6
Step 2: Add 3x to both sides.
12x−15+3x=−3x+6+3x
15x−15=6
Step 3: Add 15 to both sides.
15x−15+15=6+15
15x=21
Step 4: Divide both sides by 15.
15x
/15
=
21
/15
X= 7/5
