<h2>1)</h2>

(x - 4) {}^{2}  - 28 = 8 \\ (x - 4) {}^{2}  = 8 + 28 \\ (x - 4) {}^{2}  = 36

This must be true for some value of x, since we have a quantity squared yielding a positive number, and since the equation is of second degree,there must exist 2 real roots.

\sqrt{(x - 4) {}^{2} }  =  ± \sqrt{36}  \\x - 4 = ±6 \\ x _{1}- 4 = 6 \:  \:  \:  \:  \:  \:  \: \:  \:  \:  x _{2}- 4 =  - 6 \\ x_{1} = 6 + 4 \:  \:  \:  \:  \:  \:  \:  \:  \:  \: x_{2} =  - 6 + 4 \\ x_{1} = 10 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \: \:  \: x_{2} =  - 2

<h2>2)</h2>

Well he started off correct to the point of completing the square.

(x - 3)  {}^{2}  = 16 \\ x - 3 = ±4 \\  \: x_{1}  - 3 = 4 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: x_{2}  - 3 =  - 4 \\ x_{1}  = 7 \:  \:  \:  \:  \:  \:  \:  \:  \:  \: x_{2}  =  - 1

Colin invests £3300 into his bank account.
lorasvet [3.4K]

Answer:

$3714.18

Step-by-step explanation:

From the question;

Amount invested is $3300

Rate of interest 3% per year compound interest

Time is 4 years

We want to determine the amount that accrued after 4 years

In this case we are going to use the compound interest formula;

That is;

A=P(1+(\frac{R}{100})^nwhere A is the amount, P is the principal , r is the rate of interest and n is the time taken.

Therefore;

Amount=3300(1+(\frac{3}{100})^4\\             = 3300(1.03)^4\\             = 3300(1.1255)\\             = 3,714.179

= $3714.18

Therefore, the amount accrued after 4 years is $3714.18
