Sladkaya [172]

Answer:

2, 9 , 16 , 23 , 30 ......

Step-by-step explanation:

$a_n = 7n - 5$

$a_1 = 7*1 - 5 = 7-5 = 2\\\\a_2 = 7*2 - 5 = 14 - 5 = 9\\\\a_3 = 7*3 - 5 = 21 - 5 = 16\\\\a_4= 7*4 - 5 = 28 - 5 = 23\\\\a_5= 7*5 - 5 = 35 - 5 = 30$

Which of the following is the quotient of the rational expressions shown here?

alisha [4.7K]

Answer:

x^2 /(x^2 -36)

Step-by-step explanation:

x/(x-6) ÷ (x+6) /x

Copy dot flip

x/(x-6) * x/(x+6)

x^2/ ( x-6)(x+6)

This is the difference of squares( a-b)(a+b) = a^2 -b^2

x^2 /(x^2 -36)

If the measure of 1 is x and the measure of <2 is x+50, what is the measure of <4?

marin [14]

Answer:

Measure of angle 4 is 115°

Step-by-step explanation:

First, we want to find the measure of angle 2, because the measure of angle 2 is equal to angle 4. When 2 straight lines cross each other, the angles formed are always equal to the angle right across from it.

Find angle 2 by setting up an equation:

$x+x+50=180$

This is basically saying that angle 1 plus angle 2 equals 180°. In a half turnaround, the angle is 180°. Angle 1 and 2 make up a half turnaround.

Solve the equation:

$x+x+50=180$

Combine the 2 x's to get 2x.

$2x+50=180$

Subtract 50 from both sides.

$2x=130$

Divide both sides by 2.

$x=65$

Since x=65, plug 65 into x in the measure of angle 2 (x+50).

65+50=115.

Since Angle 2 is equal to angle 4, angle 4 is also 115.
