Answer:
- A-B=7x-3x+10-4x²-66+4
- 4x-52-4x²
hope it helps
stay safe healthy and happy.
Lets take (-4) - (-6)
= -4 + 6 (here we changed the sign because in integers when you are subtracting <span>an integer, we put its opposite..thats the rule .)
=. -4 + 6 = 2
so here we got the answer as 2 .....this shows that </span>your answer will be less than the integer you started with ....this is because here in subtraction we will first change the sign and then follow the same rules of addition ...so here if both the numbers have opposite signs then we subtract and put the greater number sign .....

Hope i am right !!!</span>
Answer:
mean
Step-by-step explanation:
mean .
mean is regarded as the average value calculated from a data set .
mean = total sum of values / total number of values.
First you need to know some rules 2 numbers that are the same with coefficients divided : you differentiate those coeff
and multyplied :you sum up them
12x^8/3x^3= 4x^8-3=4x^5
20^2x=20^x*20^x
m^5*m^-7=m^5-7=m^-2
Shifting a graph up by c units involves adding c to the whole function
therefor
y=ax^2+c is c units higher than y=ax^2 (aka, it is shifted c units up)
