Answer:
The answer is b.) -5.2 degrees
Step-by-step explanation:
to find the mean of this problem you have to add all numbers and then divide it by how many numbers there is.
so you have to add -42+ -17+14+-4+23 and that'll equal -26
so you take -26 and divide it by 5 because thats how many numbers their are to divide
-26 divided by 5 is (-5.2)
Answer:
b. x^2+4x
Step-by-step explanation:
So since you don't know the width, you can just represent it as a variable, and in this case that variable will be "x". Now using this variable we can use it to represent the length since there is a relationship between the width and length which is given. Since the length is 4 feet greater than the width, we can represent the length as (x+4). Now to find the area, we simply multiply the length * width, which is x * (x+4) = x^2 + 4x
The coefficient is: "1" .

Note: There is an "<u>implied coefficient</u>" of "1"; since "1", multiplied by any value, is equal to that exact same value; by convention, we eliminate the "1" as a coefficient.

(x+p)(x−q) = x² − xq + px − pq ;

(x+p)(x−q) = {using "FOIL" → "First, Outer, Inner, and Last" terms}:

<u>I</u>nner: p*x = px ;
<u>L</u>ast: p*(-q) = -pq

(x + p)(x − q) = x² − xq + px − pq .

The information to fill one the box regarding the proof include:
- AB = CD
- AD = CB
- BD is common to both triangles
<h3>How to illustrate the proof?</h3>
It should be noted that when two triangles of each corresponding sides are equal, then it's said that they are similar.
Here AB = CD, and AD = CB as they illustrate the fact that they are parallel.

Answer:
a = a
b = b
c = c
Step-by-step explanation:
Formula: 
C is always the largest number
<em><u>a times a + b times b = c times c</u></em>
