Answer:
x = - 2 or x = 4
Step-by-step explanation:
the expression inside the absolute value can be positive or negative
Removing the bars and solve x - 1 = ± 3
x - 1 = - 3 or x - 1 = 3
x - 1 = - 3 ( add 1 to both sides ) ⇒ x = - 2
x - 1 = 3 ( add 1 to both sides ) ⇒ x = 4

Answer:
18 units
Step-by-step explanation:
Area of rhombus is given by 1/2(product of length of diagonals).
Given
Area of rhombus = 90 sq. units
length of one diagonal = 10 units
let the length of other diagonal be x units
Substituing the value given above in formula for area of rhombus we have
90 = 1/2(10*x)
=> 90*2 = 10x
=> 180 = 10x
=> x = 180/10 = 18
Thus, length of other diagonal is 18 units.
