The simplified expression for the given function is 2x + 4 - ( 1 / x-1). The correct option is A.

<h3>What is an expression?</h3>

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the functions are f(x) = x + 2 and h(x) = 1 / x-1. The value of the function 2f(x) – h(x) will be calculated as,

E = 2f(x) – h(x)

E = 2( x + 2 ) - ( 1 / x-1)

E = 2x + 4 - (1/x-1)

<h2>Answer:</h2>

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expressions.</h3>

$f(x) = x + 2\\\\h(x) = \frac{1}{x-1}$

<h3>2. Write the operation.</h3>

$2(x+2)-(\frac{x}{x-1} )$

<h3>3. Apply the associative property of multiplication.</h3>

$(2)(x)+(2)(2)-(\frac{x}{x-1} )\\ \\2x+4-\frac{x}{x-1}$

<h3>4. Express your result.</h3>

$2f(x)-h(x)=2x+4-\frac{x}{x-1}$

[NEED THIS ANSWERED QUICKLY]<br> What is the surface area of the triangular prism?

pochemuha

<u>Given</u>:

The base of the triangle is b = 3 feet.

The height of the triangle is h = 4 feet.

The other side of the triangle is 5 feet.

The height of the triangular prism is 20 feet.

We need to determine the surface area of the triangular prism.

<u>Surface area of the triangular prism:</u>

The surface area of the triangular prism is given by the formula,

$SA=bh+(s_1+s_2+s_3)H$

where b is the base of the triangle,

h is the height of the triangle,

s₁ , s₂ and s₃ are the sides of the triangle and

H is the height of the triangular prism.

Substituting the values, we get;

$SA=(3)(4)+(3+4+5)(20)$

$SA=12+(12)(20)$

$SA=12+240$

$SA=252 \ ft^2$

Thus, the surface area of the triangular prism is 252 ft²

Draw the graphs of the lines below on the same grid to find the coordinates of the point of intersection. y + 5 = 2 x y = 7 − 2

Butoxors [25]

Answer:

The point of intersection is (3,1)

Step-by-step explanation:

Manipulate these equations to achieve the form of y = mx + c

1) y + 5 = 2x

Y = 2x - 5

2) y = 7 - 2x

Y = -2x + 7

Point of intersection is (3,1) on the graph attached

To check algebraically:

2x - 5 = -2x + 7

4x = 12

X = 3

Substitute to get y

Y = 2x - 5

Y = 2 x 3 - 5

Y = 1

Therefore (3,1)
