Answer:
parallelogram, quadrilateral
Step-by-step explanation:
a rectangle is a quadrilateral because it has 4 sides.
it is a a parallelogram because it has two sets of parallel lines in those four sides.
in order for a quadrilateral to be a rhombus, all sides must be the same length. (if a rectangle is a rhombus, it is a square.)
Answer:
The solutions are -0.65 and 4.65.
Step-by-step explanation:
3x^2 - 12x = 9
Divide both sides by 3
x^2 - 4x = 3
To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2. So add 4 to both sides.
x^2 - 4x + 4 = 7
(x-2)^2 = 7
x - 2 = (square root) of 7
x = 2 (+/-) (square root) of 7.
x = {-0.65, 4.65}
The solutions are -0.65 and 4.65.
hope this helps:)sorry if it doesnt
Answer:
Option B,C and E are solution to given inequality 
Step-by-step explanation:
We need to check which ordered pairs from given options satisfy the inequality 
Ordered pairs are solutions to inequality if they satisfy the inequality
Checking each options by pitting values of x and y in given inequality
A ) (1, -5)

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
B) (-3, - 2)

So, this ordered pair is solution of inequality as it satisfies the inequality.
C) (0, -9)

So, this ordered pair is solution of inequality as it satisfies the inequality.
D) (2, -1)

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
E) (5, 4)

So, this ordered pair is solution of inequality as it satisfies the inequality.
So, Option B,C and E are solution to given inequality
