Answer 2
9(2n + 1)

Distribute 9 to the terms in the brackets.

18n + 9

Add = 0 to solve for x

18n + 9 = 0

Move 9 to the other side by subtracting

18n = -9

Divide by 18 on both sides

n = -9/18

Simplify

n = -1/2

In decimal form the answer can also be -0.5 depending on your question.

Hope this helped!

Answer:

[tex]x=4[/tex], [tex]y=61[/tex]

Step-by-step explanation:

Since the triangles are congruent, we already know that they have the same angles and sides.

We can solve for the missing side with this equation:

[tex]51=12x+3[/tex]

subtract [tex]3[/tex] from both sides

[tex]48=12x[/tex]

divide both sides by [tex]12[/tex]

[tex]x = 4[/tex]

Due to the Angle Theorems we already know [tex]2[/tex] of the angles on the triangle:

[tex]63[/tex] and [tex]56[/tex]

We can solve for the missing angle with this equation:

[tex]A+B+C=180[/tex]

[tex]63+56+y=180[/tex]

[tex]119+y=180[/tex]

subtract [tex]119[/tex] from both sides

[tex]y=61[/tex]

Answer:

x=-2

Step-by-step explanation:

5x+4=-6 so basically what you want to do is try to get x by itself

step 1 subtract 4 from each side

5x=-10

step 2 divide each side by 5

x=-2

5x + 4 = -6
-4 -4
5x = -10

Answers:

Sam's current age = 24The mother's current age = 48

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

Explanation:

s = Sam's age right now

2s = the mother's age right now, since she is twice as old as Sam currently.

In 12 years time, Sam will be s+12 years old.

12 years ago from this current year, the mother was 2s-12 years old.

Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value

Set the expressions equal to one another and solve for s.

s+12 = 2s-12

s-2s = -12-12

-s = -24

s = 24

Sam is currently 24 years old.

His mother is currently 2s = 2*24 = 48 years old.

12 years ago, his mother was 2s-12 = 48-12 = 36 years old.

12 years from now, Sam will be s+12 = 24+12 = 36 years old.

Since we get 36 each time, this confirms we have the correct answers.

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.
