This would be easiest to do by completing the square.
x^2+10x-2=0
x^2+10x=2
x^2+10x+25=27
(x+5)^2=27
x+5=±√27
x=-5±√27
(x+5+√27)(x+5-√27)
that other answer is a virus dont click it
cell wall : gives plant cell its shape, rigid
cell membrane: more selectively controls what goes in and out of the cell, acts like a skin
dunno about grid
The answer would be 90 degrees because 15 minutes are between 2:00 and 1:45 and that is a quarter of an hour and so a quarter of a circle is 90 degrees
Answer:
$ 1,350
Step-by-step explanation:
i = (prt) / 100
p = $ 1,200 r = 2.5% t = 5 years
i = (1,200 x 2.5 x 5) / 100
i = $ 150
amount = p + i
= 150 + 1,200
= $ 1,350
Answer:
$34.40
Step-by-step explanation:
this equation has 3 steps
1. to find out how much the dvds cost without any discount or tax: $40
2. the price of the dvds with the 20% discount, which can be found with cross-multiplication making the price after discount $32
3. the final price of the dvds with sales tax can be found also with cross-multiplication and the final answer would be 34.4
