Answer:
The question is unclear, but if the book store sold 9 copies total, they sold 2 yesterday.
Step-by-step explanation:
I am not sure how many copies were sold in total but here is how you can solve it- Get the total amount of copies and subtract the number of copies sold in total. Then get the difference and subtract 7 from it. The difference is your answer.
The factorization of 12a^3b^2 +18a²b^2 – 12ab^2 is 
<u>Solution:</u>
Given, expression is 
We have to factorize the given expression completely.
Now, take the expression
Taking 
as common term,
Taking "a" as common term,
Taking "6" as common term,
Splitting "3a" as "4a - a" we get,
Hence, the factored form of given expression is
Answer:
9
Step-by-step explanation:
I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
Answer:
Inequaliy: 2x-3(12)>60
X>48
Step-by-step explanation:
Since area of a rectangle is W(L)=A
The inequality given right here including length And width and area Plugged in would be
2x-3(12)>60. (It’s >60 because the area stated in the problem said to be greater then 60 so we put a Greater then sign)
Combine like terms and solve
2x-36>60
Add 36 on both sides
2x>96
Divide 2 on both sides to isolate variable
x>48
Check:
2(50)-36>60 ( I used 50 because it’s greater then 48 and it’s a easy number to work with for just a check)
solve:
100-36>60
64>60✔️
