Factorise fully :

4(x - y)^2 - 9(x + y)^2​

- ( 5x + y ) ( x + 5y )

or

-5x^2 - 5y^2 - 26xy

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
