W=l-8
a=9
a=lw
9=(l-8)l
9=l²-8l
0=l²-8l-9
factor
0=(l-9)(l+1)
set to zero
l-9=0
l=9
l+1=0
l=-1, false length can't be negative
l=9
the length is 9 units long
Should be the second one.
Answer:
<h3>$189,292.92</h3>
Step-by-step explanation:
Using the compound interest formula to get the equivalent amount after 5 years;
A = P(1+r/n)^nt
P is the principal = 120,000
r is the rate = 10% = 0.1
t is the time = 5 years
n is the time of compounding = 1/2 = 0.5(semi annual interest)
Substitute into the formula;
A = 120,000(1+0.1/0.5)^(5)(0.5)
A = 120,000(1+0.2)^2.5
A = 120,000(1.2)^2.5
A = 120,000(1.5774)
A = 189,292.92
Hence the company issue is $189,292.92
5x + 2/2 = 2x - 1
2/2 is basically 1 so
5x + 1 = 2x - 1
isolate the variable
5x + 1 = 2x - 1
-1 -1
5x = 2x -2
-2x -2x
3x = -2
solve
3x/3=-2/3
x=-2/3
