Answer: Radical conjugate.

Step-by-step explanation:

By definition  a+\sqrt{b} and a-\sqrt{b} are called "Conjugate radicals".

Therefore, by this definition, you can know the following:

1) a+\sqrt{b} is the conjugate of a-\sqrt{b}

2) a-\sqrt{b} is the conjugate of a+\sqrt{b}.

Then, since you know that 3+\sqrt{11} is a root of a polynomial function, therefore you can conclude that the name given to the other root 3-\sqrt{11} of the same function is the following:

"Radical conjugate".

Order the sides of each triangle from shortest to longest.
Oksana_A [137]

Answer:

FG, GH, FH

Step-by-step explanation:

H=180-100-50=30°

Since H is the smallest degree, the side opposite it (FG) is the shortest length.

Since F is the middle degree, the side opposite it (GH) would be the middle length.

Since G is the highest degree, the side opposite it (FH) would be the longest.

FG, GH, FH

Write as a single term: sin(25°) cos(10°) − cos(25°) sin(10°).
eduard

Answer: cos (25° + 10°)

Step-by-step explanation: The expression:

sin(25°) cos(10°) − cos(25°) sin(10°)

is associated to the expression for the cosine of the sum of two angles that is:

cos (α+β) = sinα *cosβ -cosα*sinβ

Hence if we do α = 25° and β = 10°

by subtitution we get:

cos (25° + 10°) = sin(25°) cos(10°) − cos(25°) sin(10°)

2/3 (x - 7 ) = -2<br> AL y = 5/3 B: 8 1/3 C: 10 D: 4
nika2105 [10]

Answer:

D: 4  

Step-by-step explanation:

1. Solve the equation

\begin{array}{rcl}\dfrac{2}{3}(x - 7) & = & -2\\\\2(x - 7) & = & -6\\x - 7 & = & -3\\x & = & \mathbf{4}\\\end{array}

2. Check

\begin{array}{rcl}\dfrac{2}{3}(4 - 7) & = & -2\\\\\dfrac{2}{3}(-3) & = & -2\\\\-2 & = & -2\\\end{array}

OK
