Answer:

option c, x = 3

Step-by-step explanation:

Given:

f(x) = 27

f(x) = $3^{x}$

Since both equal f(x) they must be equivalent as well,

$3^{x} = 27\\$

Apply exponent rule, 3 x 3 x 3 = 27

hence x = 3

If a parallelogram has diagonals that are perpendicular bisectors of each other, what is the most descriptive name for it?

Feliz [49]

Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.

Question 2 Multiple Choice Worth 5 points)

DerKrebs [107]

Answer:

√20 units.

Step-by-step explanation:

Please see attached photo for diagram.

The other leg of the triangle is x as shown in the attached photo.

Using the pythagoras theory, we can obtain the the value of x as follow:

x² = 4² + 2²

x² = 16 + 4

x² = 20

Take the square root of both side.

x = √20 units

Therefore, the value of the other leg x of the triangle is √20 units
