If you would like to find the rational roots of x^4 + 8 * x^3 + 7 * x^2 - 40 * x - 60 = 0, you can do this using the following steps:
x^4 + 8 * x^3 + 7 * x^2 - 40 * x - 60 = 0
(x^2 - 5) * (x^2 + 8 * x + 12) = 0
(x^2 - 5) * (x + 6) * (x + 2) = 0
1. x = - sqrt(5)
2. x = sqrt(5)
3. x = - 6
4. x = - 2
The correct result would be -6 and -2.

An estimate of the number of defective televisions that are made each day is 150.
<h3>How many defective televisions are made each day?</h3>
The first step is to determine the ratio of the televisions sampled to the total number of televisions produced each day.
1000 / 40 = 25
The second step is to multiply, 25 by 6: 25 x 6 = 150

70/6 × 18/4
70 * 18/6*4. cross out 18 and 6.
= 70*3/4
= 35 * 2 * 3/ 2*2
= 35*3/2
= 105/2
= 52.5
OR
52 1/2.
Answer:
41.135
Step-by-step explanation:
$34.99+3 =$37.99
to add sales tax all you got to do is multiple $37.99 to the tax percentage (8.25%) so it's 37.99*8.75% then add the original price back. so it's 37.99*8.75%+37.99=41.124175
if you round to 38 the answer is 41.135
