Using formula: <span>A=Pi*r^2
A would represent the area of the whole mural but we would plug in r as 25, 50 is the whole width half of it is 25 which is the radius. the whole circle has a degree of 360 but we need the area of 38 degree.</span><span>
A=38/360*pi*25^2
=16.57</span>
The quadratic equations are solved and answered below -
<h3>What is a equation?</h3>
An equation is a mathematical statement showing the equivalence of two mathematical expressions. Example -
3x + 5 = 8
Given is -
3x² - 7 = 31
2x² + 18 = 0
4x² - 26 = - 50
2x² + 36 = x²
We have -
3x² - 7 = 31
3x² = 38
x² = 38/3
x² = 12.67
x = ±3.56
2x² + 18 = 0
2x² = - 18
x² = -9
x = ±3i
4x² - 26 = - 50
4x² = - 24
x² = -6
x = ±√6i
2x² + 36 = x²
x² = - 36
x = ±√6 i
Therefore, the quadratic equations are solved above.

Parallel lines has equal slopes.
Equation of the line 2x + y + 1 = 0 in slope intercept form is y = -2x - 1 with slope of -2. Therefore, the slope is -2.
Actual length of the room
6 * 40
240 inches
Actual width of the room
4 * 40
160 inches
Area of the room
240 * 160
