Step-by-step explanation:
cos(40)=x/4
The perimeter of a triangle is the sum of its side lengths.
The weight of the each pile yesterday would be 6 and 8 pounds.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given;
Yesterday the ratio of seeds in these piles was 3:4.
Let it be 3x and 4x.
If the 2 pounds of seeds is added in the bigger pile, then it become
4x + 2
He also ate 1/4 pound from the smaller pile, then
3x - 1/4
Now the quantities of seeds in those piles is in the ratio of 5:16.
So, 4x + 2 = 5x
3x - 1/4 = 16x
Solve;
So, 4x + 2 = 5x
2 = 5x - 4x
x = 2
The weight of the each pie would be
3x = 6 pound
4x = 8 pound
Hence, The weight of the each pile yesterday would be 6 and 8 pounds.

Answer:
x = -1, 0, 2
Step-by-step explanation:
p(x) = 5x³ − 5x² − 10x
Factor the greatest common factor:
p(x) = 5x (x² − x − 2)
Now factor the quadratic. You can use the AC method, the quadratic formula, the rational root test, or trial and error.
p(x) = 5x (x − 2) (x + 1)
Finally, set each factor equal to 0 and solve for x.
5x = 0 → x = 0
x − 2 = 0 → x = 2
x + 1 = 0 → x = -1
