(14 over 5) · (15 over 5)
= 14·13·12·11·10/5! · 15·14·13·12·11/5!
= 6012006
(n over k) is the Binomial coefficient
Answer:
21x + 12
Step-by-step explanation:
Distribute
3(7x) = 21x 3(4) = 12
21x + 12
So that’s the answer cuz like terms cannot b combined with numbers
8.5x + 55 = 123
You would use the formula: mx + b = y
The slope is the amount of money each day(mx),and the y-intercept would be the fee(b) and the total cost would be y.
y =2x
