Prove that the value of the expression is not divisible by 6 for any whole n:
(2n+1)(n+5)–2(n+3)–(5n+13).
Answer:
Step-by-step explanation:
(2n+1)(n+5) - 2(n+3) - (5n+13) = 2n² + 4n - 14 (*)
+) if n is divisible by 3 ⇒ n= 3k ⇒ (*)⇔ 2.9k² + 4.9k -14
2.9k² + 4.9k = 3( 2.3k² +4.3k) ║ 3 but 14∦3
⇒ with n =3k, (*)∦ 3 (1)
+) if n = 3k + m (m∦ 3)
⇒ (*) ⇔ 2.(3k+m)² + 4.(3k+m) -14 = 2.9k² + 2.3k.m + 2m² + 4.3k + 4m -14
= 3(2.3k² + 2.km + 4k) +2m² + 4m -14
3(2.3k² + 2km + 4k)║3 but (2m²+4m-14)∦3
⇒ with n = 3k+m, (*) ∦ 3 (2)
(1)(2)⇒ [(2n+1)(n + 5) - 2(n+3) - (5n+13)] ∦ 3
⇒ (2n+1)(n+5)–2(n+3)–(5n+13) is not divisible by 6 for any whole n

6x + 1 = 3(2x – 4)
2 – 5x = 7x – 12
4(3 – x) = 2(6 – 2x)
5(x + 2) = 2(x – 4)
–4(x + 3) = 4(–x – 1)
Answer:
1 and 5
Step-by-step explanation:
1. 6x + 1 = 3(2x - 4)
6x + 1 = 6x - 12
6x + 13 = 6x
-6x -6x
13 = 0x
no solution
2. 2-5x = 7x - 12
2 = 12x - 12
14 = 12x
1 1/6 = x
3. 4(3 - x) = 2(6 - 2x)
12 - 4x = 12 -4x
-4x = -4x
x = ∞
4. 5(x + 2) = 2(x - 4)
5x + 10 = 2x - 8
3x + 10 = -8
3x= -18
x = -6
5. -4(x + 3) = 4( -x - 1)
-4x -12 = -4x -4
-4x - 8 = -4x
-8 = 0x
no solution
Answer:

Answer:
1 is congruent to 2 due to vertical angles
3 is congruent to 4 due to vertical angles
therefore, if 1 is congruent to 4, 3 must be congruent to 2
another way to do it is:

Triangles
An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.
The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:
8x+3=67
Reducing:
8x=67-3=64
Solving:
x=64/8
x=8

The table above shows the high temperature last Thursday for five cities, A through E. If the median of the Thursday high
temperature for these cities was 81°F, which of the following could NOT have been the high temperature last Thursday of city
A?
Answer:85
Step-by-step explanation:
[tex]F[/tex]High temperature last Thursday of city is [tex]85[/tex]°
(A) is correct. If the median of the Thursday high temperatures for the five cities was[tex]81[/tex]°[tex]F[/tex],then the five high temperatures are listed in order from greatest
to least (or least to greatest),
A.[tex]85[/tex]°[tex]F[/tex]
B.[tex]75[/tex]°[tex]F[/tex]
C.[tex]65[/tex]°[tex]F[/tex]
D.[tex]55[/tex]°[tex]F[/tex]
Since the three greatest known high temperatures are [tex]91[/tex]°[tex]F[/tex]., [tex]87[/tex]°[tex]81[/tex]°[tex]F[/tex].
[tex]81[/tex]°[tex]F[/tex] must be the third temperature in the list.The unknown high temperature for City A must be less than or equal to[tex]81[/tex]°[tex]F[/tex].
Thus, [tex]85[/tex]°[tex]F[/tex] is NOT less than or equal to [tex]81[/tex]°Therefore only [tex]85[/tex]°[tex]F[/tex] could NOT have been the high temperature last Thursday for City A.For more information,

given g(x)=0.5x^2-5x+3.5, find g (4a)
Answer:
g(4a) = 8a^2 -20a +3.5
Step-by-step explanation:
Put 4a where x is and simplify.
g(x) = 0.5x^2 -5x +3.5
g(4a) = 0.5(4a)^2 -5(4a) +3.5
= 0.5(16a^2) -20a +3.5
g(4a) = 8a^2 -20a +3.5
