Which statements about a square are always true?

- Two angles are obtuse.

No.  There are no obtuse angles in a square.

- All sides are equal.

No.  It's true of squares AND rhombuses.

- Two or more angles are right angles.

Yes.  Always true for a square, sometimes true for a rhombus.

- More than two sides are parallel.

Confusing, so call it a 'no'.

In both squares and rhombuses, every one of the four sides

is parallel to ONE other side.

Another important note:

Look at the statement that's true always for a square and sometimes for a rhombus:

"Two or more angles are right angles".

WHEN does a rhombus have right angles in it ?  Fasten your seat belt and hold on tight:

A square is a special kind of rhombus.  It's a rhombus that has right angles in it.

So a rhombus has right angles in it when it's a square.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
