Answer:
3y=0
Step-by-step explanation:
(2y+6) (y-6)=0
first you are going to remove the bracket
so: 2y+6 y-6 =0
then you are going to arrange them
so: 2y+y =6-6
then you're going to do your addition
so: 2y + y = 3y
while 6-6=0
so therefore the answer who be 3y=0
The expressions 100×10 and the more complicated
(100 - 4a)(10 + a)
are calculating annual (expected) revenue. In 100×10 the 100 is the number of decks and the 10 is the price per deck. In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck. So a must be the amount the price increases.

Answer:
120:300 is in the same ratio as 2:5. Can you add the pound sign? My keyboard does not have it.
Step-by-step explanation:
Add the two parts of the ratio together
2 + 5 = 7
Find 5:7
5:7 = x:420
5/7 = x/420 Cross multiply
7x = 5 * 420 Combine the right
7x = 2100 Divide by 7
x = 2100/7
x = 300
Find the second number
420 - 300 = 120
120 : 300 is the answer
Divide top and bottom by 60
120/60 = 2
300 / 60 = 5
