Answer:.

A total of 5 expressions can be simplified to 4n + 8.

Step-by-step explanation:

1. 2n + 2(n + 4)

= 2n + 2n + 2.4

= 4n + 8

2. $ \textbf{4(n + 1)} + \frac{ \textbf{4n}}{\textbf{n}} $

= 4n + 4 + 4

= 4n + 8

3. 2³ + n³ + n

Since. 2³ = 8 we have:

8 + n³ + n

≠ 4n + 8

4. 5(n - 1) - (n - 13)

= 5n - 5 - n + 13

= 4n + 8

5. 4n + 8

= 4n + 8

6. $ \frac{\textbf{10(4 + 2n)}}{\textbf{5}} $

= 10.2(2 + n)/5

= 2.2(2 + n)

= 4(2 + n)

= 8 + 4n

= 4n + 8

7. (2n + 1)² - 4n²

= 4n² + 2.2n . 1 + 1² - 4n²

= 4n² + 4n + 1 - 4n²

= 4n + 1

Hence, the answer.

CRITICAL THINKING The total area of the polygon is 176 square feet. What is the value of $x$ ?
Katarina [22]

Answer:

x = 6

Step-by-step explanation:

this figure involves two triangle and one rectangle

for area of rectangle= Length * Width = 16 * 8 = 128 feet^2

for area of one triangle = 1/2 * base * height = 1/2 * x *8 = 4x

for two triangles = 8x ft^2 total

whole area = two triangles + one rectangle

176 = 8x + 128

8x =48

x = 6

PLEASE HELP! IT'S DUE IN 30 MINTUES!.. :)

The equation that best describes the distance traveled is y = 190 + 65x.

Finding the values of the variables that lead to the stated equality being true is a step in the process of solving an equation with variables. Equation solutions are the amounts of the unknowns that meet the equality, whereas unknowns are the variables with which the equation must be solved.

Identity equations and conditional equations are the two types of equations. For every possible value of a variable, an identity holds true. The variables in a conditional equation can only have certain values.

An equation is made up of two expressions connected together by an equals symbol ("=").

The Distance traveled by car is 190 miles

The Speed of the car is 65 miles per hour.

Let x be the total number of hours traveling by car and y be the total distance remaining.

Then,

Total distance = 190 miles + 65 miles per hour × Number of hours traveled.

y = 190 + 65x

Consequently, the equation is y = 190 + 65 x.
