= 20y + 3y -4(-2y)
= 20y + 3y + 8y
= 31y
In short, Your Final Answer would be 31y
Hope this helps!
Step-by-step explanation:
T=D/S
D=360m
S=12m/s
360m÷12m/s
Time=30s
The length of the diagonal of the square is 22.05 units
<h3>How to find the diagonal of a square?</h3>
A square have all its sides equal to each other.
Therefore, using Pythagoras theorem,
c² = a² + b²
c² = (9√3)² + (9√3)²
c² = 81 × 3 + 81 × 3
c² = 243 + 243
c² = 486
square root both sides
c = √486
c = 22.045407685
c = 22.05 units

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.
