Answer:
(8x² + 10x -4) pages
Step-by-step explanation:
2x² + 5x – 3 + 5x – 3 + 6x²+ 2
2x² +6x² +5x +5x -3-3+2
8x² + 10x -4
Anytime you subtract a negative number, it changes it to adding a positive number.
-2 + 0.7
Since we are adding, we will have an arrow going to the right
-2 + 0.7 = -1.3
Therefore, we will have a point starting at -2, an arrow pointing to the right and stopping at -1.3
Best of Luck!
Answer:
You need to rent 14 videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.
Step-by-step explanation:
Let Number of videos to be rented be x;
Given:
For non members;
Cost of renting 1 video = $4
Cost for renting x videos = 
For Members;
Membership cost = $21
Cost of renting 1 video = $2.50
Cost of renting x video = 
We can create an equation. Say the number of videos you rent is given by x
. We can write that, if we rent x videos without membership, we'll have to pay
. If we rent the same amount of videos with membership, we'll have to pay
.
Hence the equation can written as

Hence You need to rent 14 videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.
The answer is o+ Hope this helped.
The probability of 2 heads:
105:500
This can be simplified further. If you divide them both by 5, you get:
21:100
That is the answer, as it cannot be simplified any further.
The probability of one head:
275:500
This can be simplified further. If you divide them both by 25, you get:
11:20
That is the answer, as it cannot be simplified any further.
The probability of no heads:
120:500
This can be simplified further. If you divide them both by 20 you get:
6:25
That is the answer, as it cannot be simplified any further.
So:
a) 21:100
b) 11:20
c) 6:25
