Answer:
x^2-1
Step-by-step explanation:
you must use the distributive property
first you do x•x=x^2,
then you do x•1 and x•-1 to get x and -x and those cancel out,
the you do 1•-1=-1, then you put it together to get x^2-1
In math problems, "of" usually means "multiplied by."
(owed to sister) = 0.2*(earnings)
.. = 0.2*$324.65
.. = $64.93
Rhoads owes her sister $64.93.
If the decimal is in the tenths then the denominator would be like 10. Ex: Decimal: 0.2 Fraction- 2/10. and the same with hundredths, thousandths, etc.
The given equation is an equation of a circle where the number after the equal sing is the radius squared.
To find the radius take the square root.
Radius = SQRT(169)
Radius = 13 units.
