21(2-x)+12=44
multiply 21 by everything inside parentheses first
(21*2)+(21*-x)+12=44
42-21x+12=44
combine like terms
(42+12)-21x=44
54-21x=44
subtract 54 from both sides
-21x= -10
divide both sides by -21
negative divided by negative becomes positive
x= 0.476
Check:
substitute x=0.476 in equation
21(2-x)+12=44
21(2-0.476)+12= 44
21(1.524)+12= 44
32.004+12=44
44=44

Answer:
Remember what a right triangle is. A right triangle is a triangle that has one right (90 degree) angle.
Recall the Pythagorean Theorem. The Pythagorean Theorem tells us that for any right triangle with sides of length a and b, and hypotenuse of length c, a2 + b2 ...
Look at your triangle, and label the sides "a," "b," and "c". Remember that the longest side of the triangle is called the hypotenuse.
