Cross multiply...
Thus,
x(x+4)=(x+12)(x+8)
expand...
x^2+4x=x^2+8x+12x+96
Simply both sides of the equation.
x^2+4x=x^2+20x+96
simply further by adding ask like terms...
-16x=96
Solve for x by making x the subject.
therefore
x=-6.
The value of her investment at the end of 3 years is £10955.08
<h3>How to determine the value?</h3>
The given parameters are
- Principal, P = £5000
- Rate, r = 6%
- Time, t = 3 years
The value is then calculated as:
Value = P * P(1 + r)^t
So, we have:
Value = 5000 + 5000 * (1 + 6%)^3
Evaluate the expression
Value = 10955.08
Hence, the value of her investment at the end of 3 years is £10955.08

Answer:
C
Step-by-step explanation:Only one that makes sence just look at the graph
The answer is 84 7/12
You would convert the mixed fractions to improper fractions then multiply the numerators and denominators. Then you convert your answer back into a mixed fraction.
7 1/4 is equal to 29/4
11 2/3 is equal to 35/3
29/4 • 35/3
So 29 • 35 = 1015 and 4 • 3 = 12
Now you have the improper fraction 1015/12, which is 84 7/12 as a mixed fraction in its simplest form.
