That picture is trying to tell us the area is

A = x² - 12x + 36

A = (x - 6)²

Since for a square

A = s²

s² = (x - 6)²

s = |x - 6|

Answer: |x-6|

Be sure to clearly label each part of your response as Part A, Part B, and Part C.

Answer:

Part A: y = 3x

Part B: The relationship of y to x is y is 3 times as much as x.

Part C: (0,0), (1,3), (2,6), (3,9), (4,12)

Step-by-step explanation:

Part A: The product of x and 3 (3 times x) is (equals) y. So we can write this linear equation as y = 3x.

Part B: The linear equation is a representation of the relationship between y and x. Y is equivalent to three times x.

Part C: To create solutions to the linear equation, simply plug in a value of x to output a y.

x = 0 -> y = 3(0) = 0; (0,0)

x = 1 -> y = 3(1) = 3; (1,3)

x = 2 -> y = 3(2) = 6; (2,6)

x = 3 -> y = 3(3) = 9; (3,9)

x = 4 -> y = 3(4) = 12; (4, 12)

Cheers.

Find the ratio of the trig function indicated.

Andrew [12]

Answer:

$\huge\boxed{\bf\:Ratio = 4:5}$

Step-by-step explanation:

We have a right angled triangle given.

At first, let's note that, sin θ = oppposite side of the triangle / hypotenuse of the triangle.

Now, in the given triangle, from the view of ∠θ,

Opposite side of the triangle = 8
Hypotenuse = 10

Then,

$\sin \theta = \mathrm{\frac{opposite \: side}{hypotenuse}}\\\sin\theta = \frac{8}{10}\\\sin\theta = \frac{4}{5}\\\\\\\Longrightarrow \boxed{\mathrm{Ratio = 4:5}}$

Why is the answer B? Plz explain.

Ivanshal [37]

Step One

Develop a formula for the perimeter.

Argument

What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.

The "perimeter" [Circumfrence] of a whole circle = 2*pi*r

We are told that whatever you call this the perimeter is 8pi + 16

Step Two

Set up the equation

8pi + 16 = 2*pi*r + 4r Including the line connecting these two.

Step Three

Take out the common factors on the left and right.

8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2

8 = 2r Divide by 2

4 = r

Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.

I don’t really understand this can someone help please?

Sidana [21]

Answer:

23 degrees

Step-by-step explanation:

So basically you plug in -10x + 58 = 111 and then solve for x. You then plug x into 6x +41. Thats how you find the angle measure. Plz award brainliest
