Answer:
f(x)=x-2x+3; f(x)=-bx
x-2x=3=-bx
x+4x+3=0
(x+3) (x+1) = 0
x=-3 or x=-1
when x+-3. f(x)=b x(-3)=18
x=-1. f(x) = - b x (-1) = b
so system of equations : ( -3, -18)
; (-),b

Well, for number three. You know that the length of the RECTANGULAR garden is 6.8 meters. Since it is a rectangle the garden will have 4 sides:two lengths and 2 widths. an easy way to find the width is to multiply the single length by 2, so 6.8 meters becomes 13.6. Then, you subtract that from the total perimeter, this leaves you with 7 meters. Those 7 meters are the sum of both width sides added together, so all you have to do is divide 7 by 2 to get 3.5 meters as your width. Before I go on do you understand how I got that number?
Answer:
The correct option is;
A. All rhombuses are parallelograms. Parallelograms have 2 pairs of parallel sides. Therefore, all rhombuses have 2 pairs of parallel sides
Step-by-step explanation:
A rhombus is a quadrilateral that has all 4 sides, it has equal opposite angles and perpendicular diagonals that bisect one another as well as having a pair of opposite parallel sides making it a parallelogram
A rhombus is similar to a parallelogram which also has equal opposite and parallel sided and equal opposite angles and the diagonals of a parallelogram also bisect each other.

Select the unit rates
Unit rate involve two items where the first item being measured can be any positive number, but the second item must be measured in units (i.e. 1)
For clarity:
If
represents unit rate, then 
Having said that:
Only
