Answer: x = 7
Step-by-step explanation: In order for a parallelogram to be a square, the angles at the corners must be 90 degrees, and the diagonals that bisect the corner angles must be 45 degrees.
4x + 17 = 45 Subtract 17 from both sides.
4x = 28 Divide both sides by 4
x = 7
Answer: 13, 15, 21, 38, 52
because The total length of two sides of a triangle is always greater than the length of the third side => 34 + 19 > x
⇔ x < 53
=> x ∈ {13; 15; 21; 38; 52}

Step-by-step explanation:
The food and drink( orginally carbon compunds) we take in are broken down into carbon compounds and most simplest being glucose (C6H12O6). When this glucose reacts with oxygen it forms carbon dioxide and water. So, this where CO2 comes from in the body. Energy is also released in the reaction which why we feel energetic after having food. This process is called cellular oxidation.
