2y° + x° + y° + 2x° + (180-33)° = 360°

3x + 3y + 147 = 360

3(x+y) = 360 - 147

3(x+y) = 213

x+y = 71

2y + 2x + K = 180

2(x+y) + K = 180

2 *71 + K = 180

142 + K = 180

K = 38°

the last one

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
