Hey !
I am going to explain what I did to get the answer...
I multiplied $29,160 by 30 = $874,800
Then I multiplied $84,460 by 30 = $2,533,800
Then I subtracted the results = a difference of $1,659,000
So the answer to your question is, $1,659,000 is the difference.
I hope I was able to help you out :D <span />
Dude, it's impossible to solve without the pic
2x+1=13 x=6 so an ok answer would be: 2x+10=40 x=15
Remember, |n|≥0 for all real numbers n
so
-|x|=0
times -1
|x|=0
true, x=0, has a solution
|x|=-15
false, can't have negative absolute value
-|x|=12
|x|=-12
false, no negative absolute value
-|-x|=9
|-x|=-9
false, no negative absolute value
-|-x|=-2
|-x|=2
x=2 or -2
true, has solutions
the ones that have no solutions are
|x|=-15
-|x|=12
-|-x|=9
Answer:
The dimension are 20 ft by 15 ft
Step-by-step explanation:
A = l*w
P = 2(l+w)
we know the area = 300
and the perimeter = 70
300 = lw
70 = 2 (l+w)
divide by 2
70/2 = 2/2 (l+w)
35 = l+w
subtract w
35-w = l+w-w
35 -w =l
substitute this into 300 = lw
300 = (35-w) * w
distribute
300 = 35w - w^2
subtract 300 from each side
0 = -w^2 +35w - 300
divide by -1
0 = w^2 - 35w + 300
factor
0= (w-15) (w-20)
using the zero product property
w-15 = 0 w-20 =0
so w=15, w=20
if w=15 then l=35 -w l = 35-15 l=20
if w=20 then l=35-w l= 35-20 = 15
The dimension are 20 ft by 15 ft
