Answer:
the answer is x=15 cm
Step-by-step explanation:
here the above given figure is a rectangle ABCD with diagonals AC and BD measuring AC= (x+10)cm and BD=(3x-20) cm
Now,
AC=BD
or, 3x-20 = x+10 [ diagonals of a rectangle are equal]
or, 2x = 30
or, x= 15 cm

It actually says the answer in the question:
"Point D is on segment BC. Segment BC measures 8x units in length. What is the length of segment BC?"
As you can see in the second sentence of the question, it states that segment BC measures 8x units in lengths.
Answer:
opening the bracket, the expression becomes
12x^2-28-19x^2
collect like terms
12x2-19x^2-28
-7x^2-28
-7(x^2+4)
