3. f(-6) = 12+1 =13

f(-2) = 4+1 = 5

f(0) =1

Range {1,5,13}

4. f(-2) = (-2)^3+1 =-7

f(-1) = (-1)^2 +1 =0

f(3) = (3)^3 +1 = 28

Range = {-7,0,28}

5.the sequence is arithmetic

d= -11+19 = 8

an = a1 + d(n-1)

an = -19 +8(n-1)

6.l =w+5

a =l*w

a(w) =(w+5) * w

a(w)= w^2 +5w

f(w) = w^2 +5w

f(8) = 8^2 +5(8)

f(8) = 64 +40

f(8) =104 in^2

Answer:

Area of rectangle = $\mathbf{x^2-4x}$

Perimeter of rectangle = $\mathbf{4x-8}$

Step-by-step explanation:

We are given:

Length of rectangle = x

Width of rectangle = x-4

We are not given if we want to find area of rectangle or perimeter of rectangle.

So, I will be finding both

Area of rectangle

The formula used is: $Area\: of\: rectangle=Length \times Width$

Putting values and finding area

$Area\: of\: rectangle=Length \times Width\\Area\: of\: rectangle=x \times (x-4)\\Area\: of\: rectangle=x^2-4x$

So, we get area of rectangle = $\mathbf{x^2-4x}$

Perimeter of rectangle

The formula used is: $Perimeter \: of\: rectangle=2(Length+ Width)$

Putting values and finding perimeter

$Perimeter \: of\: rectangle=2(Length+ Width)\\Perimeter \: of\: rectangle=2(x+ x-4)\\Perimeter \: of\: rectangle=2(2x-4)\\Perimeter \: of\: rectangle=4x-8$

So, we get perimeter of rectangle = $\mathbf{4x-8}$

I hope, it can help in solving the question.

What is the solution to the compound inequality in interval notation?

ohaa [14]

The given compound inequality is

$2(x+3)>6 \ or \ 2x+3\leq -7$

First we solve the first inequality,

$2(x+3)>6
\\
x+3 >3
\\
x>0$

Now we solve the second inequality

$2x+3\leq -7
\\
2x \leq -7-3
\\
2x\leq -10
\\
x\leq -5$

So we have

$x > 0 \ or \ x\leq -5$

So the required solution is

$( - \infty,-5] \ or \ (0, \infty)$

Correct option is A .
