well, the movie lasted 1:38 so.... and she finished it at 1:10pm.
1:10pm minus 1 hour? 12:10pm.
12:10 pm minus 10 and minus 28 minutes? 12:10 - 00:10 = 12:00pm, 12:00 - 00:28 minutes = 11:32am.
Best to factor 5 out of the first 2 terms:
5x^2-7x+2=0 => <span>5(x^2 - [7/5]x) +2=0
Take half of [-7/5]: That'd be -7/10.
Square 7/10, add it to </span>5(x^2 - [7/5]x) +2=0 and then subtract it:
5(x^2 - [7/5]x)+ 49/100 - 49/100 ) +2=0
Then we have 5(x- [7/10] )^2 - 49/100 ) + 200/100 = 0
5(x-7/5)^2 - 245/100 + 200/100 = 0
5(x-7/5)^2 - 45/100 = 0
Dividing all terms by 5, x-7/5 = plus or minus sqrt( 9/100 )
x-7/5 = plus or minus 3/10
Then one root is x = 7/5 + 3/10, or x= 17/10 (answer #1)
The other is x = 7/5 - 3/10, or x = 14/10 - 3/10, or x = 7/10 (answer #2)
Answer:
don't know
Step-by-step explanation:
Answer:
WDQA
Step-by-step explanation:
Notice that angle P has two arc marks. Look for the same marks in the other polygon: angle W has two arc marks. So P and W are corresponding angles.
Repeat for the rest of the letters:
G → D
Y → Q
X → A
Matching each letter, the similarity statement is:
PGYX ~ WDQA
