Answer:
80
Step-by-step explanation:
let w = the width of the rectangles
then
12w = the area of one rectangle
8w = the area of other
:
12w - 8w = 320
4w = 320
w = 320/4
w = 80 units wide
;
:
Check
12 * 80 = 960
8 * 80 = 640
--------------
difference: 320
I'm pretty sure the above fractions are equivalent because if you reduce 5s/15t then it equals s/3t.

Answer:
Step-by-step explanation:
yes....the pair of linear equations has unique solution.....
2x + 3y - 7 = 0 ...... (i)
3x + 2y + 10 = 0 ....... (ii)
on comparing the equation i nd ii with a1x + b1y + c1 = 0
nd a2x + b2y + c2 = 0 reslectively......
a1 = 2 ; b1 = 3 ; c1 = -7
a2 = 3 ; b2 = 2 ; c2 = 10
here....its clear that......
a1 / a2 is not equal to b1 / b2
Therefore the given pair of linear equation have a unique solution........
1) Factor and simplify:
f(x) = [10x (x^2 - x - 1) ] / [ 2x (x^4 - 1) ] =5 (x^2 - x - 1) / (x^4 - 1)
2) Calculate limits
A) limit of f(x) when x -> 0 = 5(-1)/(-1) = 5
=> y-axis is not an asymptote and A is TRUE.
B) Lim of f(x) when x -> +/- ∞ =
5 * (x^2 / x^4 - x / x^4 - 1/ x^4 ) / (x^4 / x^4 - 1 /x^4) = 0 / ∞ = 0
=> x-axis is an asymptote and B is TRUE
C) Lim of f(x) when x -> - 1 =
5 * (x^2 - x - 1) / (x^4 - 1) = 5 * (1 + 1 - 1) / (1 - 1) = 5 / 0 = ∞
=> x = - 1 is an asymptote and C. is FALSE.
Now you have the answer.
If you want you can verify that the last option is TRUE.
I also enclose a picture showing the asymptotes which may help you.
Answer: Option C. is the false one.
