Answer:
364.
Step-by-step explanation:
14C3 = 14! / 11! 3! which simplifies to:
14*13*12 /3*2*1
= 14*13* 2
= 364.
Answ
$11.00
Step-by-step explanation:
A quick way to do this would be as follows: 1.10 ( 0.50*$20), or $11.00.
0.50($20) gives us the sale price (at half off); that's half of $20, or $10.
The total due is then $10 (item cost) plus $1 (tax), or $11
Answer:
x=√139-3, x=-√139-3
Step-by-step explanation:
to complete the square, you first move the constant to the other side of the equation-its already done for you!
now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.
What you do to one side has to be done with the other.
x^2+6x+9=130+9
now you can factor the square:
(x+3)^2=139
squareroot both sides:
x+3=√139
x+3=-√139
now subtract both sides by 3
x=√139-3
x=-√139-3
