Answer:

4pq(p³+q³)

Step-by-step explanation:

Exactly 5 game would be when 4 wins and 1 loss of a particular person

loss has to be one of the first 4 games

A wins: qp⁴ + pqp³ + p²qp² + p³qp

= qp⁴ + qp⁴ + qp⁴ + qp⁴ = 4qp⁴

B wins: pq⁴ + qpq³ + q²pq² + q³pq

= pq⁴ + pq⁴ + pq⁴ + pq⁴ = 4pq⁴

A wins or B wins:

4pq⁴ + 4qp⁴ = 4pq(q³+p³)

Find each product.<br><br> (5-x2+2)(-3)<br><br> PLEASE HELP!!! ASAP!!!
Bumek [7]

Answer:

3x^2 - 21 (did you mean for the equation to be (5 - x^2 + 2) \cdot -3?)

Step-by-step explanation:

Multiplying -3 by each term:

-3 \cdot 5 = -15

-x^2 \cdot -3 = 3x^2

-3 \cdot 2 = -6

-15-6 = -21

So the equation comes out to 3x^2 - 21 .

Hope this helped!

Please answer quickly, what is the measure of c
goldenfox [79]
<h3>Answer: B. 140</h3>

===================================================

Explanation:

The only given number here is the 20 degree angle. So we'll start with that. This is an inscribed angle, which doubles to 2*20 = 40, and this is the measure of the arc the inscribed angle cuts off (inscribed angle theorem). Consequently, it means that central angle b is also 40 degrees.

With b = 40, we can see that c = 180-b = 180-40 = 140. This is because b+c = 180 as the two angles are supplementary.
