Answer:
A)SA= 2(1/2bh)+(lw)+(lh)+(wh)
= 2(1/2*7*24)+(22*24)*(7*22)+(22*24)
= 2(84)+528+154+528
= 168+528+154+528
=1378m^2
B) V= πr^2h
= π*10^2*20
= π*100*20
= 6283.2cm^3
A. (f + g)(x) = f(x) + g(x) = 4x - 5 + 3x + 9 = 7x + 4
B. f.g (x) = f(x) * g(x) = (4x - 5)*(3x + 9) = 12x^2 + 36x - 15x - 45
= 12x^2 + 21x - 45
C Replace the x in f(x) by g(x):-
= 4(3x + 9) - 5
= 12x + 36 - 5
= 12x + 31
7a expression: 12 + (- 1) + (- 1) + 3
7b evaluate: 13 Solving:((12 + -1 = 11) + (-1 + 3 = 2) (11 + 2 = 13))
7c: At the end of the three days, the value of the stock was $13.
