HELP ASAP PLEASE???!!!

Answers

You need to start by multiply all terms by (x-2)(x+1) and cancel

x(x+1)(x-1)(x-2)=-1(x-2)(x+1)

2x²-2x+2=-x²+x+2

Now you need to subtract -x²+x+2

2x²-2x+2-(-x²+x+2)=-x²+x+2-(-x²+x+2)

3x²-3x=0

Now factorize

3x(x-1)=0

3x=0 or x-1=0

x= 0 or x=1

an employess new salary is 28,140 after getting 5% raise what was salary before increase _and what was last years salary _?

Answers

He got a 5% raise, so 28,140 is 105% of what it used to be.

105% means 1.05

(1.05) x (salary before increase) = 28,140

Divide each side by 1.05 :

Salary before increase = 28,140 / 1.05 = 26,800 .

The rest of the question is nonsense. The salary
before increase IS last year's salary.

What fraction of a full turn is 1 degree

Answers

$1^\circ$ is equal to $(1)/(360)$ of a full turn.

A full turn, or a complete rotation, is $360^\circ$ . To get the fraction of a turn equivalent to $1^\circ$ , we have to divide by $360^\circ$ .

We can express it as an equation, then solve the equation

$1 turn=360^\circ\n(1)/(360)turn=1^\circ$

So, $1^\circ$ equals to $(1)/(360)$ of a full turn.

a full turn is 360 degrees. so 1 degree of 360 degrees written as a fraction would be 1/360.

Which information is needed to show that a parallelogram is a rectangle?

Answers

If you know for a fact that it's a parallelogram, then you only
need to show that any one angle is a right angle (90 degrees),
and that will prove that it's a rectangle.

If a parallelogram has right angles (angles with measures of 90 degrees) for all its angles, it is a rectangle.
