To solve for x, you need to isolate/get x by itself in the equation:
Square ² both sides to get rid of the square root √

x - 2 = 0 Add 2 on both sides
x - 2 + 2 = 0 + 2
x = 2
Answer:
4
Step-by-step explanation:
Assign x for the number. Write an equation.
2x = 6+.5x (I'm guessing you means "6 more than half that number")
1.5x = 6 -->
x = 4
Answer:108.54
Step-by-step explanation:
Answer:
Step-by-step explanation:
11 degrees to radians: 1 degree =57.296 radians
L = (11 degrees)/(57.296) x (11 in) = 2.111848 in
Find the area of the triangles and smal ler square and add them together ; and find the area of the complete square and set them equal to each other (these are known truths)
triangle: l×w /2
square: s^2
There are 4 triangles so
4 (1/2ab)+c^2= (a+b)(a+b)
simplify
2ab+c^2= a^2+2ab+b^2
-2ab both sides
c^2=a^2+b^2
tada!! it's proven :)
