14. Find a solution to the inequality x &gt; 6. 2 11 6 4 <br><br> help pls
stellarik [79]

Answer:

x = 11

Step-by-step explanation:

Given x > 6

This tells us that the only value that makes the inequality true is any value of x that is larger than 6

From the list 11 is the only value larger than 6, thus x = 11

11 > 6 ← is a true statement

The area of this rectangle is 3x2. What does the coefficient 3 mean in terms
Olegator [25]

The coefficient 3 means the length is 3 times the width ⇒ B

Step-by-step explanation:

The formula of the area of a rectangle is A = l × w, where

  • l is the length of the rectangle
  • w is the width of the rectangle

∵ The width of the rectangle is x

∴ w = x

∵ The length of the rectangle is 3x

∴ l = 3x

- That means the length of the rectangle is 3 time the width

  because x × 3 = 3x

∴ Area of the rectangle is A = 3x × x

∵ x × x = x²

∵ 3 × 1 = 3

∴ A = 3x²

∴ The coefficient 3 means the length is three times the width

The coefficient 3 means the length is 3 times the width

I have no idea how to do this one please help
Nuetrik [128]

Answer:

a = -14

Step-by-step explanation:

We are given

\frac{2a+38}{5} = 2\\

We want to get the variable by itself. First, we can multiply both sides by 5 to get rid of the fraction

\frac{(2a+38)(5)}{5} = (2)(5)\\2a + 38 = 10

Now we can isolate the variable by subtracting 38 from both sides

2a + 38 - 38 = 10 - 38\\2a = -28\\a = \frac{-28}{2}\\a = -14
