The simplified polynomial after standard form will be;

⇒ - 8x² - 43x - 36

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The algebraic expression is;

''The expression (3x + 6)² is subtracted from x² - 7x.''

Now,

We can formulate as;

⇒ (x² - 7x) - (3x + 6)²

⇒ x² - 7x - (9x² + 36x + 36)

⇒ x² - 7x - 9x² - 36x - 36

⇒ - 8x² - 43x - 36

Thus, The simplified polynomial after standard form will be;

⇒ - 8x² - 43x - 36

How do you find volume of sphere, cylinder, cone ? ... explaining please
boyakko [2]

Answer:

hmmmm

Step-by-step explanation:

Cone

The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together. The answer will be written in units³.

Sphere

The volume of a sphere is ⁴/₃ × π × r³. To calculate the volume we multiply these values together. The answer will be written in units³.

Cylinder

The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together. The answer will be written in units³. It is more accurate to use π = 3.142 or the π button on a calculator.

   A cone is a 3D shape with 2 faces and one edge

   A sphere is a 3D shape. It has one continuous face and no edges

   A cylinder is a type of prism. It has 3 faces and 2 edges

F(x) = -7x - 1<br> f() = -8
xxMikexx [17]

Answer:

  f(1) = -8

Step-by-step explanation:

Apparently, you want the argument of the function such that the function value is -8. Fill in the given information and solve for x:

  -8 = -7x -1

  -7 = -7x . . . . add 1

  1 = x . . . . . . . divide by -7

Now, you know that ...

  f(1) = -8

MatroZZZ [7]

Answer:

it's D

Step-by-step explanation:

it's d because if 74 would be the same as the left side next to x and if you turn that into a problem like 180-74 and I got 180 cause half of a circle is 180 and then my answer would be 106 I'm not good at explaining but it's d
