What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

f ( x ) = 3x - 7

Now , substituting the value of f ( x ) = 20 , we get

when x = c

f ( c ) = 3c - 7

The value of the equation f ( c ) = 20

Substituting the value in the equation , we get

3c - 7 = 20

On simplifying the equation , we get

Adding 7 on both sides of the equation , we get

3c = 27

Divide by 3 on both sides of the equation , we get

c = 9

Therefore , the value of the variable c = 9

Hence , The value of c so that the function f ( c ) = 20 is when c = 9

Which statement about the picture below is true

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?

sum = (360)(8) = 2880°
sum = (360)(10) = 3600°
sum = (180)(8) = 1440°
sum = (180)(10) = 1800°

Answers

Correct answer is:

1800°
the correct answer is 1440.

The equation to find the sum of interior angles in a polygon is s = 180(n-2), n being the amount of sides and s being the sum. To solve you would do s = 180(10-2), s = 180(8), and s = 1440. hopefully that makes sense haha. use the equation s=180(n-2) :))
