while excluding 0, the product and quotient is positive if operating between same sign, otherwise if we operating different sign will resulted negative.
<u>Answer-</u>

<u>Solution-</u>
Rational Root Theorem-

All the potential rational roots are,

The given polynomial is,

Here,

The potential rational roots are,


From, the given options only
satisfies.
2.40
5.40-2.40= 3 (price of 2 sodas)
8.70 - 7.20 = 1.5 (price of 1 soda)
The soda prices match up so a hamburger is 2.40
Answer:
x = 55
Step-by-step explanation:
For PQ and RS to be parallel then
∠ACQ = ∠RDB ( Alternate exterior angles ), thus
3x - 65 = 2x - 10 ( subtract 2x from both sides )
x - 65 = - 10 ( add 65 to both sides )
x = 55
