Answer:
im not very sure but i think its A or C
24x + 8 would be the anwser
Answer:
9/2 inches or 4 1/2
Step-by-step explanation: Try to find the unit rate FIRST. Divide 2 on both sides and you will get that ONE INCH = 3/2 miles.
Since you need to know the distance for 3 inches, MULTIPLY both SIDES by 3, and you will get 3 INCHES = 9/2 MILES.
A because you distribute the -8 to get -80x-(-24)
Answer:
x³ + x² − 4x + 6 = 0
Step-by-step explanation:
Imaginary roots come in conjugate pairs. So if 1+i is a root, then 1−i is also a root.
(x − (-3)) (x − (1+i) (x − (1−i)) = 0
(x + 3) (x² − (1+i) x − (1−i) x + (1+i) (1−i)) = 0
(x + 3) (x² − x − ix − x + ix + 1 − i²) = 0
(x + 3) (x² − 2x + 2) = 0
x (x² − 2x + 2) + 3 (x² − 2x + 2) = 0
x³ − 2x² + 2x + 3x² − 6x + 6 = 0
x³ + x² − 4x + 6 = 0
