Eliminate the 5’s because they cancel each other out.
Add 3p + 2p to get 5p
5p= 65
Divide by 5
P = 13
Answer:
x=7
Step-by-step explanation:
CD=DA
5X-6=3X+8
5X-3X=8+6
2X=14
X=7
This is not an arithmetic sequence.
It does not go up or down by the same amount each time.
It is a geometric sequence
it is multiplied by 5 each time
Let the hall be A=1. For 3 hours 16 people can decorate the hall. Then P1=A\(t1.number people1) P=1/48. That is for 1 person. You have 24 people to decorate the same hall. Their P2 will be (1/48).24=1/2. t2=A/P2=2 hours
The quadratic has one root with multiplicity 2 if the discriminant is 0, which is
(That is, for a quadratic 
, the discriminant is 
.)
Set the discriminant equal to 0 and solve for 
:
