Find the value of x in the given ratio 2x/21=12/18
2 answers:
You can use something called crossed multiplication (not sure the official name but something like that) basically when you have 2 fractions that equal to each other, you can multiply the numerator on the left-hand side with the denominator on the friction on the right side. and repeat the same with the numerator on the right side and multiply it by the denominator on the left. that way, there will be no more fractions and will just leave you simple algebraic equations.

ANSWER
True
EXPLANATION
According to the Rational Roots Theorem,the rational roots of a polynomial function F(x) can be written in the form
,
where p is a factor of the constant term of the polynomial, and q is a factor of the leading coefficient.
The polynomial must be written in standard form.
This means the polynomial must be written in descending powers of x.
The leading term is the first term of a polynomial written in standard form.
The constant term is the term independent of x.
