Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. a2 − 28a + 192 = 0

a = 16 or a = 12

Step-by-step explanation:

Given quadratic equation,

Step 1 : Move constant term to the right side,

Step 2 : Add the square of the half of the coefficient of x on the both sides,

Step 3 : Plug the terms in the left side into the quadratic formula,

Step 4 : Taking log both sides,

Step 5 : Isolate the variable,

Hence, the solution of the given equation is,

a = 14 + 2 or a = 14 - 2

a = 16 or a = 12

step-by-step explanation:

no solution.

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
