Perform indicated operations on left side
x*x+4x+4x+4*4=9
x^2+4x+4x+16=9 combine like terms on left side
x^2+8x+16=9 subtract 9 from both sides
x^2+8x+7=0 factor
x^2+x+7x+7=0
x(x+1)+7(x+1)=0
(x+7)(x+1)=0
x=-1, -7
Answer:
Step-by-step explanation:
What you are asking is to fill in the blank in the following sentence.
_______ % off this imported futon.
Solution
500 x/100 = 425 Divide the left by 100
5x = 425 Divide both sides by 5
5x/5 = 425/5 Simplify
x = 85
That is not the answer. That is the % paid.
The reduction is 100% - 85% = 15%
So your blank would contain 15%
Check
15% of 500 = 15/100 * 500 = 75 which is what they the store is offering you off.
Step-by-step explanation:
Let S be the sample space
S={HH, HT, TH, TT}
n(S)= 4
A: both the coins with some place
B: both the coins with different place
C:at least one tail
D:at the most one head
1) A={TT,HH}
n(A)=2
P(G)= n(A)/n(S)
= 2/4
= 1/2
2) B ={HT, TH}
n(B) = 2
P(B) = n(B)/n(S)
= 2/4
= 1/2
3) C= {HT, TH, TT}
n(C)=3
P(C) = n(C)/n(S)
= 3/4
4). D={HT, TH}
n(D) = 2
P(D) = n(D)/n(S)
= 2/4
=1/2
Answer:
122
Step-by-step explanation:
the real answer is 121.53846153846153, but you wanted to round to nearest percent
