Answer:
The value of Mary's investment after two years = £12362.7
Step-by-step explanation:
P = Principal / initial amount
R = rate of interest per cent per year
T = number of years
A = final amount at the end of T years
Then:
A = P*(1 + R/100)^2
In our example:
P = £12000
R = 1.5 per cent per year
T = 2 years
Thus:
A = 12000*(1 + 1.5/100)^2
   = 12000*(1 + 0.015)^2
   = 12000*(1.015)^2
    = 12000*(1.030225)
    = 12362.7
Value of investment after two years = £12362.7

(2) 2x 
Bc you’re adding the imaginary one infront of the x.
(1) X squared + 25
Distribution 
(3) 15x-30 
Distribution
(1) x to the 6 power
You add the powers when they are being multiplied 
(2) 2x squared + 7x + 12 
Foil method
(2) 9x + 20
Adding Like terms 
(4) 12x + 25
Adding and multiplying like terms
(2) 19x + 7
Multiplying then adding like terms. 
I hope this helps ;)
Mark me brainliest please! ;D
