Answer= x³+4x²+16x+64
Expand the following:(x + 4 i) (x - 4 i) (x + 4)
(x - 4 i) (x + 4) = (x) (x) + (x) (4) + (-4 i) (x) + (-4 i) (4) = x^2 + 4 x - 4 i x - 16 i = -16 i + (4 - 4 i) x + x^2:
-16 i + (-4 i + 4) x + x^2 (4 i + x)
| | | | x | + | 4 i
| | x^2 | + | (4 - 4 i) x | - | 16 i
| | | | (-16 i) x | + | 64
| | (4 - 4 i) x^2 | + | (16 + 16 i) x | + | 0
x^3 | + | (4 i) x^2 | + | 0 | + | 0
x^3 | + | 4 x^2 | + | 16 x | + | 64:
Answer: x^3 + 4 x^2 + 16 x + 64
Answer:B
y=13cos(1/13x)+13
Step-by-step explanation:
A-yes
B-No
C-yes
Between A-C
715=448+(3x)
715-448=3x
267=3x
267/3=x
89=x
89 students
Lets find the common demoninator of them all, Its 30! so 1/3 of 30= 10
3/5 of 30= 18 7/10 of 30= 21 1/2 of 30 = 15
So that means that 7/10 is the biggest out of them all, That means carlos ran the greatest distance!
