Answer:

= 14

Step-by-step explanation:

x = x + 22 - 8

x = x + 14

x = x + 14

x - x = x + 14 - x

<h3>Answer:  112</h3>

=========================================================

Explanation:

The angle adjacent to the 146 degree angle is 180-146 = 34 degrees.

In other words, the angles 34 and 146 combine to 180. These angles are supplementary.

The tickmarks on this triangle tell us it is isosceles. The angles opposite the congruent sides are congruent angles. So the unmarked interior angles (not marked x) are 34 degrees each.

Now use the fact that any triangle has its interior angles always add to 180

x+34+34 = 180

x+68 = 180

x = 180-68

x = 112

Agata [3.3K]
If you're not sure, begin by looking for any divisor that will divide into 24a^3c and 3a without leaving a remainder.  Note that 3 is such a number, and a is another.  

Factoring out 3a from 24a^3*c and 3a, we get 3a{8a^2*c, 1}

So the GCF is 3a.

Explain why graphing the solutions of an inequality is more efficient than listing all the solutions of the inequality.
Nadya [2.5K]
The saying "A picture is worth a thousand words" comes to mind here. You can list all of the possible points in a solution region, or you can list a few points to give the general pattern. Though this method requires a bit more work than simply graphing and showing the solution shaded region. A visual is often more efficient at conveying a message especially to those who aren't proficient with algebra. I'm sure there are other reasons why graphs are the better choice, but that's all I could think of really.

5. If Amber decides to mail copies of her photos to the 45 residents of her grandmother’s assisted living facility, the new func
pav-90 [236]

Answer: please find the answer in the explanation

Step-by-step explanation:

From the information given from the question, the initial function representing her photo sharing is:

F(x) = 3(4)^2

F(x) = 3 × 16 = 48 photos

Then the new graph has an upward shift ( translation) of 45 units

The new function representing her photo sharing is:

F(x) = 3(4)^2 + 45

F(x) = 48 + 45

F(x) = 93 photos.
