9 ½ =19/2

kitchen dimensions:

23/2 * 19/2 = 437/ 4

The perimeter of a rectangle is 12x + 4. If the width is 2x,<br> the length of the rectangle is

DENIUS [597]

Answer:

4x+2

Step-by-step explanation:

Perimeter = 2(width) + 2(length). So 12x+4 = 2(2x) + 2(length) .

12x+4 = 4x + 2(length) then subtract 4x from both sides to get 8x+4 = 2(length). In order to get length by itself you need to divide both side by 2.

4x+2 = length. Hope this helps!

The length of a rectangle is 8 1/2 inches and the width is 3 1/4 inches. What is the ratio, using whole numbers, of the length t

frosja888 [35]

Short answer 34/13
Start by converting both to improper fractions.

8 1/2 = (2*8 + 1)/2 = 17/2

3 1/4 = (3*4 + 1)/4 = 13/4

Next set up a 4 layer fraction

$\dfrac{\dfrac{17}{2}}{\dfrac{13}{4} }$

Invert the lower fraction and multiply $\dfrac{17}{2}* \dfrac{4}{13}$

Cancel the 2 and the 4 leaving you with a 2 in the numerator. $\dfrac{17*2}{13} =\dfrac{34}{13}$

Answer:

Choice D.

Step-by-step explanation:

The range is the set of all y-coordinates of the points in the graph.

The graph is a wavy function that has a maximum y-coordinate of 1 and a minimum y-coordinate of -1. The y-coordinates can also be all numbers between -1 and 1. Choice A. is only the two numbers -1 and 1. That is not correct since the range comprises the numbers -1, 1, and all numbers in between -1 and 1.

Answer: Choice D.
