Answer:
w = 6
Step-by-step explanation:
Givens
Area = 90
Let the width = w
Let the length = 2w + 3
Formula
Area = L * W
Solution
Area = (2w + 3)*w
Area = (2w + 3)* w = 90 Remove the brackets.
Area = 2w^2 + 3w = 90 Subtract 90 from both sides.
2w^2 + 3w - 90 = 0
This will factor into
(w - 6)(2w + 15) = 0
Only w - 6 will = a zero that makes sense when speaking of an area
w - 6 = 0
w = 6
L = 2*w + 3
L = 2*6 + 3
L = 15
The width is 6

Answer:
a
No singular point due to the exponent in the solution
The interval is
b
NONE
Step-by-step explanation:
From the question we are told that
The generally solution is mathematically represented as
=>
integrating both sides
=>
=>
=>
Here
=>
From the above equation we see that the domain for x has no singular point the interval is
Also there is no transient term in the general solution obtained because as there no case where
Answer:
-2x + 6 8x or 5x + 3 < 9
Step-by-step explanation:
-2x + 6 8x -> x 3/5
5x + 3 < 9 -> x < 6/5
The total cost is 35000+7000=£42000. After the deposit has been deducted, £21000 remains to be paid. The amount of each instalment is 21000/20=2100/2=£1050.
