\frac{3x^3+9x^2-6x}{-3x}
Since the denominator is a monomial, we divide each term of the trinomial in the numerator by the denominator.
\frac{3x^3}{-3x} = -1x^2, because 3/-3 = 1 and x³/x = x².
\frac{9x^2}{-3x}=-3x; 9/-3 = -3 and x²/x = x.
\frac{-6x}{-3x} = 2; -6/-3 = 2 and x/x = 1, so we have 2*1  = 2.
Together this gives us -x^2-3x+2

Answer:

Step-by-step explanation:

3x + 7 + 9x - 43 = 180

                    12x = 216

                      x = 18

m∠4 = 3(18) + 7 = 61°

m∠5 = 9(18) − 43 = 119°

Calculate the distance between (4,9) and (-2,6) using the distance formula.
MAVERICK [17]

Answer:

\large\boxed{d=3\sqrt5}

Step-by-step explanation:

\text{the formula of a distance between two points}\ A(x_1,\ y_1)\ \text{and}\ B(x_2,\ y_2):\\\\|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=========================\\\\\text{We have}\ (4,\ 9)\ \text{and}\ (-2,\ 6).\ \text{Substitute:}\\\\d=\sqrt{(-2-4)^2+(6-9)^2}=\sqrt{(-6)^2+(-3)^2}=\sqrt{36+9}=\sqrt{45}\\\\\sqrt{45}=\sqrt{9\cdot5}=\sqrt9\cdot\sqrt5=3\sqrt5

Twice the difference of a number n and seven is equal to four less than the product of five and the number n. What is that value
I am Lyosha [343]

Answer:

n=-10/3

Step-by-step explanation:

"Twice the difference of a number n and seven is equal to four less than the product of five and the number n" translates into 2(n-7) = 5n - 4. To solve, isolate the variable n.

2(n-7) = 5n - 4

2n - 14 = 5n - 4

2n - 10 = 5n

-10 = 3n

-10/3 = n

If Mp =5x - 34 and 2x -4 Find MP
Aliun [14]

Answer:

Mp=24

Step-by-step explanation:

From expression 2x-4, we solve for x.

Then we have: x=4/2 → x=2

Replace x=2 in Mp=5x-34

Solve for Mp:

Mp=5x2-34

Mp=10-34

Mp=-24
