2 answers:

6 0

Example: $\frac{3}{5}+ \frac{4}{9}$
Look at the denominator of the fractions, and then see whether there is a common prime number associated with them.
In this example, since 5 and 9 (3*3) do not have any common prime numbers, you just multiply these numbers together and get 45.
There, we just found the LCD of fractions.

Answer:

Step-by-step explanation:

The diagonals of a rectangle are congruent, then

5x - 31 = 2x + 11 ( subtract 2x from both sides )

3x - 31 = 11 ( add 31 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Then

RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39

The diagonals are each 39 units

The first term in a sequence is -2 and the common ratio is 3. What is the sixth term of the sequence?

AlekseyPX

It's the Geometric Sequence.

The n-th term of a geometric sequence with initial value a and common ratio r is given by:

$a_n=a_1\cdot r^{n-1}\ for\ n\in\mathbb{N^+}$

We have:

$a_1=-2;\ r=3;\ n=6$

Substitute:

$a_6=-2\cdot3^{6-1}=-2\cdot3^5=-2\cdot243=-486$

Answer: The sixth term is equal -486.

elena55 [62]

Answer:

x = 30

Step-by-step explanation:

65 + 55 = 120

angle B must equal 60

angle B is labeled as 2x

set up equation to solve for 'x': 2x = 60

x = 30

add up all angles to make sure you get 180 degrees
