Answer: $20.01
$20.99
$20
$80
$1,000
Step-by-step explanation:
The reason why is because they are $20 or more. if it was $19.99 then no.
4/9*9/5 you have to reciprocate the 5/9 since you want to change division to multiplication.
So 36/45 is the answer
Answer:
180 feet
Step-by-step explanation:
|-60+120| is 180
<span>The right function is f(x)=3x^3-10x^2-81x + 28
You can realize that 7 is a root because it is in all the answers.
So you can divide the polynomial by x - 7. If you do it you can find that the quotient is 3x^2 + 11x - 4
Now you can use the quadratic formula to find the other two roots.
If you do it, you will find they are x = 1/3 and x = -4.
So the answer is option A) 7, -4, 1/3
And the polynomial can be written as (x - 7)(x + 4) (x -1/3)
