Answer:

The answer is 18

Step-by-step explanation:

18 + x really means 18 + 0, because x is equal to 0

and if 18 + x = y, it means 18 + 0 = y,

so y is equal to 18

hope this helped!

Y intercept occurs when x = 0 

so its 0-4 / 0- 4  =  1

coordinates of y intercept is (0,1)

x intercept occurs when y = 0
(x -4) / (x^2-4) = 0 

x-4 = 0
x = 4

recall your SOH CAH TOA \bf sin(\theta)=\cfrac{opposite}{hypotenuse}

cos(\theta)=\cfrac{adjacent}{hypotenuse}

% tangent
tan(\theta)=\cfrac{opposite}{adjacent}

which identity uses only

opposite
adjacent?

well, is Ms Tangent.. thus  \bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(54^o)=\cfrac{1200}{x}

solve for "x", make sure your calculator is in Degree mode, since the angle is in degrees

The length of a rectangle is 3 meters greater than 2 times the width. The perimeter of the rectangle is 30 meters.What is the le
faust18 [17]

Answer:

11 meters

Step-by-step explanation:

Lets say that  w = width of the rectangle, to start. If the length of the rectangle is 3 meters greater than 2 times the width, the length of the rectangle is equal to 3 + 2w.  

The perimeter of the rectangle is 2 * length of rectangle + 2 * width of the rectangle. With the perimeter being equal to 30 and width being w and length being 2w+3:

The perimeter of the rectangle is 2(w) + 2(2w+3) = 30.  

We first need to find out w first, which will give us the width of the rectangle. Taking it step by step, we get:

2w + 4w + 6 = 30

6w + 6= 30

6w = 24 which is done by subtracting both sides by 6 to put the variables on one side and the values on the other side

w = 4 which is done by dividing 6 on both sides

Ultimately, this gets width to be 4 meters. Now that we found the width, we need to plug w = 4 into the equation we set up for length which is 2w+3.

That being said, the ANSWER is:

length of rectangle = 2(4)+3 = 11 meters

Hope this helps! :)
