X^3 - 21x = -20add 20 to both sidesx^3 - 21 x + 20 = 0Rational Root Theorem:Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20------------------------------- Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
Triangle RST was ____________, then dilated, to create triangle ZXY.
answer is translated
<span>boys = 14x
</span><span>girls = 17x
14x + 17x = 186
31x = 186
x = 186/31
x = 6
</span>boys = 14x = 14 * 6 = 84
