X^2-6x=13
(x-3)^2-9=13
(x-3)^2=22
(x-3)= +-sqrt22
x = sqrt22+3 or x = -sqrt22+3
Answer:
Step 2
Step-by-step explanation:
Step 2 is not correct. It should be abs(25 - - 26) = abs(25 + 26) = 51
Given that Step 2 is accepted (as - 1) then three is OK and and so is 4. But technically they are incorrect as well. I think you are likely to say that step 2 is the problem.
To complete the identity, we need these fundamental identities:
Thus, by identity 1 we have:
by identity :
recall the values :
,
so:
Putting all these together, we have:
which is equal to
, by identity 3
Answer: D
Answer:
5
Step-by-step explanation:
I=PRT
I=interest
P=principal
R=rate in decimal
T=time in years
we want to find how much he earns when he invests 1250, on 5%, and how much per month, or 1/12 years
P=1250
R=0.05
T=1/12
I=1250(0.05)*(1/12)
I=62.5/12
I=5.2083333
round to nearest cent
I=$5.21
about $5.21 per month
