Answer:what are you asking
Step-by-step explanation:
I can explain when I get a question
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.
Answer: A
Step-by-step explanation:
<em>- and - = + </em>
-8 (4 - x) = 16
-32 + 8x = 16
8x = 16 + 32
8x = 48
x = 6
528 will be your answer.
Step-by-step explanation:
408 / 17 = 24
1 case = $24.00
24 x 5 = 120
408 + 120 = 528
