Answer:

3x^2 - 3x - 3

Step-by-step explanation:

Plug in the equations in place of the variables

First, subtract k(x) from h(x)

x^2+1-x-2  (combine like terms)

x^2 - x -1

Next, multiply the new equation by 3

3(x^2 - x - 1)     Use distributive property

= 3x^2 - 3x - 3

Which function's domain consists of all real numbers except -2?
mixas84 [53]

Answer:

Choice A

Step-by-step explanation:


A restriction of just a point is a hole,  which means it is in the denominator

To determine this, we look at the denominators,

B and C do not have denominators,  

Square roots cannot be negative, so they have larger restrictions

for D  x+2 ≥0

           x≥-2

Choice A  is the only option that has a restriction that is a hole

x+2 ≠0

x≠-2

Pls helpppppp thanks!!!!!!!<br> :)
Lena [83]

Answer:

If i did this right the answer would be 69

I converted the inches to feet (might be my first mistake)

so i get 2.5 X 1 X 1 to get 2.5

i then multiply that by 62.4 to get 156

then 225-156 = 69

Sari is factoring the polynomial 2x2 + 5x + 3. What is the missing number in her factorization?
sergejj [24]

Answer:

<em>The missing number in Sari's factorization is </em><em>3</em><em>.</em>

Step-by-step explanation:

The given polynomial is,

=2x^2 + 5x + 3

From quadratic equations, applying middle term factorization,

=2x^2 + 2x+3x + 3

=2x(x + 1)+3(x + 1)

=(2x+3)(x + 1)

Comparing this to the given expression, the missing number in Sari's factorization is 3.
