Which of the following is a factor of 5x3 + 320?
a. 5
b. x + 4
c. x2 − 4x + 16
d. all of the above

Option D all of the above.

Step-by-step explanation:

The given expression is 5x³ + 320

5x³ + 320 = 5 (x³ + 64)

= 5 [x³ + 4³]

= 5[( x+4 ) ( x² + 16 - 42 )]

So these are three factors 5,(x + 4) and ( x² + 16 - 4x )

Therefore, Option D all of the above is the answer.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
