Answer:
30/1000
Step-by-step explanation:
red has a chance of 3/10
purple has a chance of 2/10
yellow has a chance of 5/10
for probability, multiply the denominators together, and the numerators together
3*2*5 = 30
10*10*10 = 1000
So the probability of picking red, then purple, and then yellow with replacement is 30 of 1000
Hope this helps!

Step-by-step explanation:
we know that
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
so

where
a, b and c are the length sides of triangle
s is the semi-perimeter of triangle
we have

<em>Find the semi-perimeter s
</em>
s=
Find the area of triangle

Answer:
x^3-x^2-17x+12
Step-by-step explanation:
(x+4)(x^2-5x+3)
x^3-5x^2+3x+4x^2-20x+12
x^3-5x^2+4x^2+3x-20x+12
x^3-x^2-17x+12
