Answer:

Ok so you want to find the relationship between triangle ADEe and ABC, so you can compare 2 corresponding sides. You have the lengths of AD and AB, so to find the relationship you can do AD/AB. AD = 3 and AB = 5, so that means the relationship is 3/5. Then, you can compare DE and BC. If BC is x, you would have:

3/5 = 6/x

so you know that 3/5 = 6/10, so x= 10

Luis has 40 noah 45 nickels , 33 dimes, 10 quarters and 18 fifty-cent coins . how much money does he have

Aleksandr [31]

Answer:

$13.75 should be your answer

Step-by-step explanation:

Note that 45 nickles = 45 x 5 = 225 cents

Note that 10 quarters = 10 x 25 = 250 cents

Note that 18 half-dollars = 18 x 50 = 900 cents.

225 cents = $2.25

250 cents = $2.50

900 cents = $9

Add

2.25 + 2.50 + 9 = 13.75

If a polynomial function f(x) has roots 4 – 13i and 5, what must be a factor of f(x)?

Morgarella [4.7K]

The factor of f(x) is (x-(4-13i))

If a polynomial function f(x) has roots 4 – 13i and 5

One of the complex roots is 4-13i

If we have one complex root then there should be one more complex root.

<h3>What is the complex root?</h3>

complex roots come in pairs like (a+ib) and (a-ib)

so another complex root for 4-13i is 4+13i

If 'a' is a root then the factor is (x-a)

4+13i is a root

So the factor is (x-(4-13i))
