Answer:

d.)

Step-by-step explanation:

2w-4 is the length and the width is 3x that so:

3(2w-4)=6w-12

thats one side so the equation would be

2(2w-4)+2(6w-12)

we have the 2's in front of the parenthesis because theres two sides with length and two sides with width

Answer:

D) $\displaystyle 2(6w - 12) + 2(2w - 4)$

Step-by-step explanation:

$\displaystyle 3[2w - 4] = w → 6w - 12 = w$

Now, according to the Perimeter Formula [for rectangles ONLY], $\displaystyle 2w + 2l = P,$ there are twos factored outside each binomial because in a rectangle, there are two sets of parallel sides, therefore our answer is D).

Given the graph of a function f. Identify the function by name. Then Graph, state domain & range in set notation:A) f(x) +2B

WARRIOR [948]

The function in the graph has the name of square function.

The domain of a function is all values of x the function can have. The domain of this function is all real numbers:

$\mleft\lbrace x\in\R\mright\rbrace$

The range of a function is all values of y the function can have. The range of this function is all positive numbers, including zero:

$\mleft\lbrace y\in\R\mright|y\ge0\}$

In order to graph f(x) + 2, we just need to translate the graph 2 units up. To find the new points, we need to increase all y-coordinates by 2:

(-2, 6), (-1, 3), (0, 2), (1, 3), (2, 6)

Domain: {x ∈ ℝ}

Range: {y ∈ ℝ | y ≥ 2}

Then, in order to graph f(x) - 2, we just need to translate the graph 2 units down. To find the new points, we need to decrease all y-coordinates by 2:

(-2, 2), (-1, -1), (0, -2), (1, -1), (2, 2)

Domain: {x ∈ ℝ}

Range: {y ∈ ℝ | y ≥ -2}
