Please help I am new to this algebra expressions and I need help finding out how to do this !

a. = 3

b. = 141

c. = -12

Step-by-step explanation:

a.

2a - 3b if a = 2, and b = 1

2(2) - 3(1) = 4 - 1 = 3

b.

6d - w² if d=25 and w = 3

6(25) - 3² = 150 - 9 = 141

c.

8b/p-2 if b = -3 and p = 4

8(-3)/4-2 = -24/2 = -12

If my answer is incorrect, pls correct me!

29 is the correct answer

step-by-step explanation:

(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
