Let's solve this problem step-by-step.
−3(1−2x)=3x+3(x−3)+6
Step 1: Simplify both sides of the equation.
−3(1−2x)=3x+3(x−3)+6
(−3)(1)+(−3)(−2x)=3x+(3)(x)+(3)(−3)+6(Distribute)
−3+6x=3x+3x+−9+6
6x−3=(3x+3x)+(−9+6)(Combine Like Terms)
6x−3=6x+−3
6x−3=6x−3
Step 2: Subtract 6x from both sides.
6x−3−6x=6x−3−6x
−3=−3
Step 3: Add 3 to both sides.
−3+3=−3+3
0=0
So, 0=0 or all real numbers.
Answer:
The perimeter of a rectangle is P = 2 b + 2 h , where is the base (or width) and is the height (or length). If a rectangle is a square, with sides of length , the formula for perimeter is P s q u a r e = 2 s + 2 s = 4 s and the formula for area is A s q u a r e = s ⋅ s = s 2

Answer:
x = -7/2 or x =1
Step-by-step explanation:
2xx - 5x - 7 = 0
2x(x - 1) + 7(x - 1) = 0
(2x +7) (x -1) = 0
x = -7/2 or x =1

Answer:
x = 13
Step-by-step explanation:
First start with the blank equation
Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.
Then solve
25 + 144 = 
169 =
c = 13
