Answer:

x = 12

Step-by-step explanation:

CDEF is a cyclic quadrilateral.

• the opposite angles of a cyclic quadrilateral sum to 180° , then

3x + 6x + 72 = 180

9x + 72 = 180 ( subtract 72 from both sides )

9x = 108 ( divide both sides by 9 )

x = 12

Function a(e) represents the surface area of a cube in terms of its edge length, e, and the difference quotient is 12e 6h. what
hram777 [196]

<u> </u><u>48 square inches per inch </u><u> is the average rate of change in surface </u><u>area</u><u>.</u>

What is an area in math?

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

The surface area of a cube of side length e is:

A(e) = 6 *e².

The rate of change is:

A'(e) = 2 * 6 * e

The average rate of change between 3 in and 5 in is:

r  = (A(5in) + A(3in))/2 = (2*6*5in + 2*6*3in)/2 = 48in

Now, the options are given in:

"squere inches per inch"

This is written as:

in^2/in = in.

Then we can write our above rate as:

r = 48in = 48in^2/in = 48 square inches per inch.

PMO and LMN are vertical angles. The measure of PMO is (X + 7). The measure of LMN is 55
Reika [66]

Answer:

x= 48 and PMO= 55

Step-by-step explanation:

  PMO= LMO so 55= x+7

 x+7=55

    -7     -7

x=48    

     Pmo = x+7 so (48)+7 = 55

So. At oaknoll school 90 out of 270 students own computers. What percent of students at oaknoll school do not own computers? Rou
Arada [10]

Answer: There have 66.66..7% of Student own computer(s).

Step-by-step explanation:

What I did is make the whole school (270) be 100%, then I subtract from Whole school to own computer and the answer will be not own computer: 270 - 90 = 180, so there has 180 students who do not own computer, but we want to find the percentage. So we multiply 180 and 100, we will get 18,000! Then divide it to 270 and we will get 66.66..7, write it on top of 100, so it would be 66.66../100 which mean 66.66..% or 66.66..7%

Hopefully that’s helpful, if not then look the attachment include this answer to help better understanding. Good luck!
