Answer:

D.\frac{-6x^{2}-x-7 }{x^{2}+9}

Step-by-step explanation:

since the x^{2}+9=x^{2} +9 you just have to add \frac{-6x^{2}+x-3-2x-4 }{x^{2}+9 } so the answer will be: \frac{-6x^{2}-x-7 }{x^{2}+9 }

Alan made a small four sided table for his office .Two sides of the table are 27 inches long and 36 inches long .If the diagonal
Tcecarenko [31]

Answer:

does NOT have right angles at the corners

Step-by-step explanation:

we are given that the sides of a table are 27" and 36" long.

If we assume the table to be rectangular, then by Pythagorean formula, we can find the diagonal and compare it to the 40" that we are given.

(refer to attached)

diagonal² = 27² + 36²

diagonal² = 27² + 36²

diagonal² = 2025

diagonal = √2025

diagonal = 45 inches

because the diagonal that we found is not the same as the 40" that was given, we can conclude that the table is not a rectangle (i.e does not have right angles at the corners)

Find the limit as x approaches 0 for cos(2x) / x
zhenek [66]

We are asked to determine the limits of the function cos(2x) / x as x approaches to zero. In this case, we first substitute zero to x resulting to 1/0.  A number, any number divided by zero is always equal to infinity, Hence there are no limits to this function.

-6 - 3(2x + 4) = 18what’s the answer
Brrunno [24]

Answer:

x=-6

Step-by-step explanation:

-6-3\left(2x+4\right)=18

Add 6 to both sides:

-6-3\left(2x+4\right)+6=18+6

-3\left(2x+4\right)=24

Divide both sides by -3:

\frac{-3\left(2x+4\right)}{-3}=\frac{24}{-3}

2x+4=-8

Subtract 4 from both sides:

2x+4-4=-8-4

2x=-12

Divide both sides by 2:

\frac{2x}{2}=\frac{-12}{2}

x=-6
