What is xx plus 2x plus 3x plus 6 equal to?
X can't be solved, you don't have anything on the right side of the equal.
What is IXX squared showing all your working?
IXX (19) squared = -I(-I+XX)+XX(-I+XX) Multiplying out brackets = +I-XX-XX+CCCC Collecting like terms = -XXXX+CCCC+I (401-40) Then when simplified = CCCLXI (361) which is the correct answer. Remember that in maths a minus number multiplied by a minus number produces a plus number. Thus -I times -I is +I. David Gambell, Merseyside, England.
Is fx equals x x equals 5 a linear equation?
no, because xx=x squared, and x squared is not linear
What is 3xx plus 2 plus xx plus 4?
3xx + 2 + xx + 4 = 4xx + 6 = 2(2xx + 3)
How do you multiply 19 by 19 using roman numerals?
First of all today we write out 19 in Roman numerals as XIX but the Romans themselves would have probably calculated 19 as XVIIII and then simplified it to IXX in fact the Latin word for IXX is 'undeviginti' which literally means one from twenty. So the question is: What is IXX squared? IXX squared = -I(-I+XX)+XX(-I+XX) Multiplying out the brackets = +I-XX-XX+CCCC Collecting like terms = -XXXX+CCCC+I (401-40) When simplified = CCCLXI (361) which is the answer to your question. Note that in maths a minus number multiplied by a minus number becomes a plus number. Thus -I times -I is +I.
What is IX plus XV plus XX?
IX (9) + XV (15) + XX (20) = XLIV (44)

When 3 equals 5 plus x minus 1 what does x equal?
3 = 5+x-14 = 5 + x-1 = xx = -1
If 15 gallons of fuel is equal to 100 pounds how many gallons are in 11700 pounds?
15 gal / 100 lb = 'x' gal / 11,700 lb(15) (11,700) = 100 xx = (15) (11,700) / 100x = 1,755 gallons
What is the inverse function of xx?
XX or X*X, can be written as X squared. The inverse of a function "sort of cancels it out". I know the inverse of a square is the square root. Since we need the inverse of X squared, it's inverse is the square root of X. sqrt(x)
