Step-by-step explanation:

Add 8n to both sides to get

8n-67 = 5

then add 67

8n = 5+67 = 72

divide by 8

n = 9

write the equation for a polynomial of least degree with integer coefficients given the following zeros: -2, -6, -10i. leave you
lorasvet [3.4K]

The equation of the polynomial in factored form is (x+2)(x+6)(x-10) = 0

<h3>What is a polynomial?</h3>

A polynomial is an algebraic equation with at least the power of its variable 3.

Analysis:

if -2, -6, -10i are the zeroes of the polynomial, it means x = -2, x = -6, x = -10i

if x = -2, (x+2) is a factor, (x+6) is a factor.

convert x = -10i to a real number,

i = \sqrt{-1}

-10\sqrt{-1} = 10\sqrt{- -1} = 10\sqrt{1} = 10

x = 10, so (x-10) is a factor.

Therefore equation of the polynomial in factored form is (x+2)(x+6)(x-10) = 0

In the figure, p║ q find m∠1 <br><br> 1. m∠1 = 69<br> 2. m∠1= 50<br> 3. m∠1= 61<br> 4. m∠1 = 40
Alona [7]

Answer:

Hope this helps you.

The answer is 61, x+40+5x+14=180, so x equals 21. 5(21)+14 ends up equaling 119, so 180-119 equals 1

ASAP!!!!!
prohojiy [21]
When using substitution, you want to solve an equation for one variable that doesn’t make the equation worse to work with.

The general idea is that you want to find a variable that has a coefficient of 1 or -1.

In 2.5x - 7y = 7.5, both variables have “bad” coefficients.

In 6.2x - y = 1, the y has a coefficient of -1. That’s where you want to start.
