Find the value of x such that | x2 + 3 + |x + 3|| = (3 - x)2.
Answer x = : .
(write your answer by decimal in simplest form)
+x>-3 => x2 +x+6 =9-6x+x2 => 7x=3 => x =3/7 (TM)
+x< -3 => |x2 -x| = 9 -6x +x2 => x2 -x =9-6x+x2 => 5x = 9 => x = 9/5 loại
=> x = 3/7

Subtract 114 from 5 times the number A, the difference will be 51.8 more than 3 times the number A. Find the value of the number A.
Answer: A=
(Write your answer as a decimal in the simplest form)
114 - 5 x A = A x 3 + 51,8
5 x A = A x 3 + 51,8 + 114
A x 2 = 51,8 + 114
A x 2 = 165,8
=> A = 165,8 : 2 = 82,9

The value of ( B x C ) : A =
(write your answer by decimal in simplest form)
Từ 0->1 chia làm 4 phần nên A=0+1/4=0,25
Từ 1->2 chia làm 4 phần nên C=1+1/4=1,25
nên B=1+3/4=1,75
Nên (B+C)/A=(1,75+1,25)/0,25=3/0,25=12
