The number is 5; 5*8=50, 40-5=35
(f + g)(x) = 7x + 6 + 4x² = 4x² + 7x + 6
The notation given means to add the rules of f(x) and g(x), and since there are no like terms, your answer is 4x² + 7x + 6
Answer:
look at the picture ..........
Answer:
x= -8 x=2
Step-by-step explanation:
x^2 +6x - 6 = 10
Subtract 10 from each side
x^2 +6x -16 =0
Factor what 2 numbers multiply to -16 and add to 6
8*-2 = -16
8-2 = 6
(x+8) (x-2) =0
Using the zero product property
x+8 =0 x-2 =0
x= -8 x=2
