Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
An equation is formed of two equal expressions. The solution of the equation (5x+2)² + 15x + 6=0 is -0.4 and -1.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution to the equation,
(5x+2)² + 15x + 6=0
25x² + 4 + 20x + 15x + 6 = 0
25x² + 35x + 10 = 0
Plotting the equation on the graph, the value of x is,
x = -0.4, -1
Hence, the solution of the equation (5x+2)² + 15x + 6=0 is -0.4 and -1.
