What is 13x + 4 and how do i solve it

Simplifying

12x2 + -13x + -4 = 0

Reorder the terms:

-4 + -13x + 12x2 = 0

Solving

-4 + -13x + 12x2 = 0

Solving for variable 'x'.

Factor a trinomial.

(-1 + -4x)(4 + -3x) = 0

Subproblem 1

Set the factor '(-1 + -4x)' equal to zero and attempt to solve:

Simplifying

-1 + -4x = 0

Solving

-1 + -4x = 0

Move all terms containing x to the left, all other terms to the right.

Add '1' to each side of the equation.

-1 + 1 + -4x = 0 + 1

Combine like terms: -1 + 1 = 0

0 + -4x = 0 + 1

-4x = 0 + 1

Combine like terms: 0 + 1 = 1

-4x = 1

Divide each side by '-4'.

x = -0.25

Simplifying

x = -0.25

Subproblem 2

Set the factor '(4 + -3x)' equal to zero and attempt to solve:

Simplifying

4 + -3x = 0

Solving

4 + -3x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + -3x = 0 + -4

Combine like terms: 4 + -4 = 0

0 + -3x = 0 + -4

-3x = 0 + -4

Combine like terms: 0 + -4 = -4

-3x = -4

Divide each side by '-3'.

x = 1.333333333

Simplifying

x = 1.333333333

Solution

x = {-0.25, 1.333333333

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
