Answer:
x=13
Step-by-step explanation:
isolate the x by adding4 to each side of the equation
x - 4 = 9
+ 4 =+ 4
and then the -4 cancels out and you get x = 13
I hope this helps :)
If you are looking to simplify these equations, here is how you would go about doing so.
7w(-8+3w)
Use a property called the Distributive Property, which means multiplying the number outside of the bracket by each number inside of the brackets.
Here is how this would look:
7w(-8+3w)
-56w+21w²
Now,
6q(-4+8q)
-24q+48q²
Hope this helps.
12 is not a perfect square, but 4, a factor of 12, is a perfect square. Thus, separate the problem
sqrt(12) into factors as follows:
sqrt(12) = sqrt(4)*sqrt(2) = 2*sqrt(2) (answer)
C I think if it’s wrong I’m sorry
