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.

If you have problems with multiplying decimals:
Multiply the numbers just as if they were whole numbers.
1.Line up the numbers on the right - do not align the decimal points.
2.Starting on the right, multiply each digit in the top number by each digit in the bottom number, just as with whole numbers.
3.Add the products.
Answer:
The proportion is p = 0.399
Step-by-step explanation:
The estimate of a proportion is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
286 people captured, so D = 286.
Total outcomes:
Sample of 716 suspected criminals, so T = 716.
Proportion
12mi, you just multiply the 3mi and 4mi, i think♀️
Answer:
D!!!!
Step-by-step explanation:
To find the percent mark up, find the amount of the mark up first:
From $
21
, 450 → $
27
,
950 is an increase of $
6
,
500 To find the percent mark up:change original amount ×
100 %
6500 21450 × 100
% = 30.3
% mark up in price.
