You didn't give any choices but I am still going to solve this.

First let's separate this a little bit.

(2x+3)(x^2-7)

=2x(x^2-7)+3(x^2-7)

Now we can multiply these in again.

=2x^3-14x+3x^2-21

=2x^3+3x^2-14x-21

Answer:

Check your question again

Step-by-step explanation:

The arithmetic equation of this sequence is an=5+(n-1)*7. Replace 359 with an and solve for n

359=5+(n-1)*7, 354/7=n-1. Wait you got the whole equation wrong, the first term should be 7 so that the common difference be equal to 5

Please Help me it’s geometry

Answer:

Option C.

Step-by-step explanation:

Given: In $\Delta OPQ,m\angle O=107^{\circ},m\angle P=28^{\circ}$ .

In $\Delta OPQ$ ,

$m\angle O+m\angle P+m\angle Q=180^{\circ}$ (Angle sum property)

$107^{\circ}+28^{\circ}+m\angle Q=180^{\circ}$

$135^{\circ}+m\angle Q=180^{\circ}$

$m\angle Q=180^{\circ}-135^{\circ}$

$m\angle Q=45^{\circ}$

Now,

$m\angle O>m\angle Q>m\angle P$

In a triangle, the greatest angle has largest opposite side and smallest angle has smallest opposite side. So, we conclude that

$PQ>OP>QO$

Therefore, the correct option is C.
