Answer:

44 degrees

Step-by-step explanation:

Since they are supplementary, they add up to 180. This means that

3x - 6 + 54 = 180

Solving,

3x + 48 = 180

subtract 48 from both sides

3x = 132

divide both sides by 3

x = 44 degrees

Answer:

x ∈ {-4, 2}

Step-by-step explanation:

The x-coefficient (+2) is the sum of the constants in the binomial factors of the equation, and the constant term (-8) is their product.

Since you're familiar with the divisors of 8, you know that the two factors of -8 that total +2 are -2 and +4. These are the constants in the binomial factors:

f(x) = x^2 +2x -8

f(x) = (x -2)(x +4)

The roots of f(x) are the values of x that make these factors be zero. They are x=2 and x=-4.

The roots of f(x) are -4 and 2.

_____

Above is the solution by factoring. We can also "complete the square" to find the roots. Anytime we're looking for roots, we want the values of x that make f(x) = 0.

x^2 +2x -8 = 0

x^2 +2x = 8 . . . . . add the opposite of the constant

x^2 +2x +1 = 8 +1 . . . . . add the square of half the x-coefficient: (2/2)² = 1

(x +1)² = 9 . . . . . . . . . . . write as squares

x +1 = ±√9 = ±3 . . . . . . take the square root

x = -1 ± 3 . . . . . . . . . . . subtract 1

The roots are x=-4, x=2.

Select the correct answer from each drop-down menu. Complete the statements about these similar pyramids. Two square pyramids A

Scrat [10]

The ratio of the heights of these pyramids is 3 : 1, the ratio of the base areas is 9 : 1 and the ratio of the volumes is 27 : 1.

<h3>What is ratio?</h3>

Ratio can be defined as a mathematical expression which denotes the proportion of two (2) or more physical quantities to one another and the total quantities.

The ratio of the heights of these pyramids is given by:

Ratio = Height of pyramid A : Height of pyramid B

Ratio = (3V/lw) : (V/lw)

Ratio = 3 : 1.

The ratio of the base areas of these pyramids is given by:

Ratio = Base area of pyramid A : Base area of pyramid B

Ratio = (3a)² : a²

Ratio = 9a : a

Ratio = 9 : 1.

The ratio of the volumes of these pyramids is given by:

Ratio = Volume of pyramid A : Volume of pyramid B

Ratio = (3l × 3w × 3h)/3 : (l × w × h)/3

Ratio = 27 : 1.
