Answer:
x^3-4x^2-5x+3
explanation:
multiply each term in the parentheses by X squared
x(x^2)-4x^2-5x+3
Answer:
-5^x + 3x + 2
Step-by-step explanation:
(f - g)(x) = ƒ(x) -g(x) = -5^x -(-3x -2) = -5^x + 3x + 2
Answer:

Step-by-step explanation:
(x+1) (x−4) (x+3)
= ((x+1)(x−4)) (x+3)
= ((x+1)(x−4)) (x)+((x+1)(x−4)) (3)
= 
= 
Answer:
z = 4
y = -1
x = 2
Step-by-step explanation:
x - y = 3
Therefore => x = 3 + y
y + 2z =7
Therefore => y= 7 - 2z
We have the equation :
2x + 3y + 4z = 17
2(3 + y) + 3(7 - 2z) + 4z = 17
6 + 2y + 21 - 6z +4z = 17
2(7 -2z) - 2z + 27 = 17
14 - 4z - 2z + 27 = 17
-6z + 41 = 17
-6z = -24
z = 4
