Answer:  The correct option is (A) 5x^2-2x+4.

Step-by-step explanation:  We are given to select the polynomial that represents the following difference :

D=(8x^2+9)-(3x^2+2x+5)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the required difference, we need to subtract the coefficients of the same powers of the unknown variable x.

From (i), we get

D\\\\=(8x^2+9)-(3x^2+2x+5)\\\\=8x^2+9-3x^2-2x-5\\\\=(8-3)x^2-2x+(9-5)\\\\=5x^2-2x+4.

Thus, the required difference is 5x^2-2x+4.

Option (A) is CORRECT.

babymother [125]

Answer:

45 miles

Step-by-step explanation:

Jimenez drives 3/10 of the distance:  (3/10)(150 miles) = 45 miles.

Mr. Robertson drives 2/5 of the distance:  (2/5)(150) = 60 miles.

These two people drive 105 miles total.

Mr. Weatherly drives the rest:  (150 miles - 105 miles) = 45 miles.
