The length of extra cable that is required to connect the two pieces of existing cable is equal to 182 meters.
<h3>How to determine the length of extra cable?</h3>
In order to determine the length of extra cable that is required to connect the two pieces of existing cable, we would apply the law of cosine as follows:
B² = A² + C² - 2(A)(C)cosB
Substituting the given parameters into the formula, we have;
B² = 325.0² + 430.0² - 2(325.0)(430.0)cos23
B² = 105,625 + 184,900 - 279,500(0.9205)
B² = 290,525 - 257,279.75
B² = 33,245.25
B = √33,245.25
B = 182.33 ≈ 182 meters.

Answer:
(x - 1)
Step-by-step explanation:
Given
f(x) = x³ - 2x² - 19x + 20
The sum of the coefficients is 1 - 2 - 19 + 20 = 0
This means that x = 1 is a root and (x - 1) is a factor of f(x)
<span>Hey there, Lets solve this step by step.

<span>"Two times the quantity of a number minus 12”
</span><span>Two times the quantity = 2 * n
</span>
<span>number minus 12 = n - 12
</span>
Therefore
2n-12
