Answer:
3 x^4 + -75
Step-by-step explanation:
Expand the following:
3 (x^2 + 5) (x^2 - 5)
(x^2 + 5) (x^2 - 5) = (x^2) (x^2) + (x^2) (-5) + (5) (x^2) + (5) (-5) = x^4 - 5 x^2 + 5 x^2 - 25 = x^4 - 25:
3 x^4 - 25
3 (x^4 - 25) = 3 x^4 + 3 (-25):
3 x^4 - 25×3
3 (-25) = -75:
Answer: 3 x^4 + -75

Let (15+x) and (22+x) be the future ages of the brothers
15+x+22+x= 408
Collect like terms
37+2x=408
Move 37 to the other side as a negative number
2x=371
Divide both sides by 2
371/2 is 185.5
So, after 185.5 years, their ages will add up to be 408
Answer: 6
Step-by-step explanation:
n/3 - 8 = -2
Multiply 3,
n3 -24 = -6
add 24 to -6
n3 = 18
divide by 3
n = 6
Answer:
C: (x + 4)(x - 1)
Step-by-step explanation:
Please use " ^ " to indicate exponentiation. Thanks.
x2 + 3x – 4 → x^2 + 3x - 4 = (x + 4)(x - 1) This matches Answer C.
