twice a number plus 40 equals a sum minus 2
2-(2x+40) or (2x+40)-2
Step-by-step explanation: If you wanted to solve the problem, you have to do the stuff in the parentheses before you do the stuff out of the parentheses. In the parentheses, you will have to solve 2x before you do anything else. When you solve 2x, the answer to that, add it to 40. Then the answer in the parentheses, subtract it by 2 and you can get the answer.
x = 17
in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:
3x - 24 = x + 10
solving this equation for x to get:
3x - x = 10 + 24
2x = 34
x = 34/2
x = 17
therefore, the value of x = 17.
