If the areas of rectangles A, B, and C are 11, 33, and 75, respectively. Then the area of the rectangle D will be 25 square units.

<h3>What is a rectangle?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

In the figure below, the areas of rectangles A, B, and C are 11, 33, and 75, respectively.

Then the area of the rectangle D will be

Let a be the length and b be the width of the rectangle D. Then we have

The ratio of the area of the rectangles will be

\rm \dfrac{A_A}{A_B} = \dfrac{A_D}{A_C}\\\\\\A_D  = \dfrac{A_A \times A_C}{A_B}\\\\\\A_D = \dfrac{11 \times 75}{33}\\\\\\A_D = 25

More about the rectangle link is given below.

Using the distributive property to find the product (y - 4x)(y ^ 2 + 4y + 16) results in a polynomial of the form y ^ 3 + 4y ^ 2
galben [10]

Answer:

a=16

Step-by-step explanation:

The distributive property states that

a(b+c)=ab+ac

Therefore using the distributive property

(y - 4x)(y ^ 2 + 4y + 16)

=y(y ^ 2 + 4y + 16) - 4x(y ^ 2 + 4y + 16)

Expanding the brackets

y ^ 3 + 4y^2 + 16y - 4xy ^ 2 - 16xy - 64x.....(i)

Comparing with the form

y ^ 3 + 4y ^ 2 + ay - 4x  y ^ 2 - axy - 64x-----(ii)

The coefficient of y in (i) is 16 which corresponds to a and the likewise the coefficient of xy

Therefore, a=16

In which type of triangle is the othocenter on the perimeter of the triangle?
Snezhnost [94]

Answer:

A right triangle

Step-by-step explanation:

It's where the altitudes all intersect. In a right triangle, the legs of the right triangle are the altitudes-- especially evident when the right angle is at the base. The altitude from the hypotenuse to the right angle also passes through the right angle.

Anybody know number 9
denpristay [2]

Answer:

  (x -2)² +y² = 16

Step-by-step explanation:

The circle has its center at (h, k) = (2, 0), and has a radius of r = 4. The standard form equation is ...

  (x -h)² +(y -k)² = r²

For the given values of (h, k) and r, this equation is ...

  (x -2)² +y² = 16

2. Find an equation for the line with slope = 0 that passes through the point (-5, 7).
mel-nik [20]

Answer:

2. y = 7

3. x = 4

Step-by-step explanation:

Slope 0 is when the line is horizontal.. has a constant coordinate

(-5,7) lies on the line so the x-coordinate is 7

Equation: y = 7

A vertical line has all same x-coordinates.

Since (4,-2) is on the line, every point had x-coordinate of 4.

Equation: x = 5
