Answer:
Step-by-step explanation:
Area A = 15square cm
Length L = x
Width w = x - 2
Area = L × w
15 = x(x - 2)
15 = x^2 -2x
x^2 -2x - 15 = 0
Solving by factorization
x^2 - 5x + 3x - 15 = 0
(x^2 -5x) + (3x -15) = 0
x(x - 5) + 3(x - 5) = 0
(x + 3)(x - 5) = 0
(x + 3) = 0 or (x - 5) = 0
x = -3 or 5
Since x can't be negative therefore x is 5cm
Length = 5cm
Width = 5-2 = 3cm
Answer:
$18360
Step-by-step explanation:
Since, the value decreased by 40%, the price is (100-40)% of 34000
= 60% of 34000
= 60/100 * 34000
= 60 * 340
= 20400 --- (Price after first year)
Since, the value decreased by 10%, the price (100-10)% of 20400
= 90% of 20400
= 90/100 * 20400
= 90 * 204
= $18360

Tried a whole bunch of odd sequences:
11 + 13 + 15 = 39
Nope too small.
21 + 23 + 25 = 69
Woah too big!
And after a few more trials found that:
17 + 19 + 21 = 51
Woohoo!
The associative property<span> is when you can add and multiply no matter which way the problem is, for example, 2+4 = 6 and 6-4= 2 or 4+2= 6 </span>
6000 x 1.10 = $6,600 x No. years = recursive
6000 x 1.10^no of years = explicit formula.
