Expand (3x)^2
When you see ^2, it means that the term(s) inside the parenthesis should be copied once, and multiplied.
(3x)^2 = (3x)(3x)
(3x)(3x) is your expanded form

Answer:
c = 2
Step-by-step explanation:
Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions

First, subtract 6 from both sides of the equation:
9c + 6 (-6) = 24 (-6)
9c = 24 - 6
9c = 18
Next, divide 9 from both sides of the equation:
(9c)/9 = (18)/9
c = 18/9
c = 2
c = 2 is your answer.

Answer:
Algebra Review: x=-4, r =5
Step-by-step explanation:
Use distributive prop;
-3x-6=6
then add 6 to both sides to get x by itself
you get -3x=12
divide both sides by -3
you get x=-4
Again do distributive prop.
-12r+24=-36
trying to get r by itself, so subtract 24 on both sides
you get: -12r=-60
then divide -12 both sides to get r by itself and you get r=5
Pythageron Theorem:
which is a^2+b^2=c^2
a=3, b=7 and c=C^2 (this is always the long side)
so then we get 3^2+7^2=c^2
9+49=c^2
opposite of sqaring is rooting
so we get sqare root of 58 or 7.6
I'm sorry I can't help you with the angles, I would suggest looking it up and Khan Acadamy is a good resource. Good Luck!
