4p+6-3 combine like terms?
amm1812

Answer:

4p+3

Step-by-step explanation:

Because 4 has the variable p next to it, 4 can not be the same as 6 or 3 because they are whole numbers. So the only thing you can do here is 6-3, which is 3.

Factor completely: 2x3 + 6x2 + 2x + 6.
Oksi-84 [34.3K]

Answer:

The correct option is A.

Step-by-step explanation:

The given expression is

2x^3+6x^2+2x+6

Taking out the common factor.

2(x^3+3x^2+x+3)

2(x^2(x+3)+1(x+3))

2(x+3)(x^2+1)

The complete factor form of given expression is 2(x+3)(x^2+1). Therefore the correct option is A.

A plane flies 1.4 hours at 150 mph on a bearing of 10. It then turns and flies hours at the same speed on a bearing of . How far
Gnesinka [82]

Answer:

The answer is "1035.76 miles"

Explanation:

The aircraft flies at 120 mph for 1.5 hours at a 10^{\circ} bearing, then flies at the very same speed at 100^{\circ} bearings for 8.5 hours.

However an angle of 100-10 = 90^{\circ} between displacements

First shifts= 1.5 \times 120 = 180\  miles.

Second shift = 8.5\times 120 = 1020\ miles.

These two shifts are at 90^{\circ} and therefore the final shift is:

\to \sqrt{180^2+1020^2}=1035.76 \ miles
