x + y = 53
x -y = 9 Adding both equations
2x = 62
x = 31 y = 22
Answer:
x°+2x°+(x-24)°=180°
Step-by-step explanation:
The sum of of the interior angles of all triangles add up to 180°
Adding x°, 2x°, and (x-24)° <em>will</em> equal 180
Therefore, an equation that can be used to solve for the missing angles is: x°+2x°+(x-24)°=180°
Answer:
x(5x²-7)
Step-by-step explanation:
5x³-7x
=x(5x²-7)
To prove your answer,let's multiply x by each term in the bracket
=x X 5x²=5x³
x X -7 =-7x
Multiply the second equation by -2. This will cancel out the y
