Start by doing a subtraction of 6 to both sides so that the equation becomes -2x^2 + 7x + 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √((7)^2 - 4(-2)(1)) ] / ( 2(-2) )
x = [-7 ± √(49 - (-8) ) ] / ( -4 )
x = [-7 ± √(57) ] / ( -4)
x = [-7 ± sqrt(57) ] / ( -4 )
x = 7/4 ± -sqrt(57)/4
The answers are 7/4 + sqrt(57)/4 and 7/4 - sqrt(57)/4.
Plan A gives you 6% interest compounded annually so after 4 years
$2000 becomes $2000*(1.06)^4 = $2524.95
Plan B gives you 13% annual simple interest so after 4 years
$2000 becomes $2000*(1+0.13*4) = $3040
so Plan B earns more

Answer:
Area of the shaded region =
Step-by-step explanation:
Area of the Shaded region= Area of rectangle - Area of the triangle
Area of the rectangle= Length * breadth
Putting the values in the formula
Area of the rectangle :
Area of the Triangle =
Base of triangle= 20 inches , Height of the triangle = 10 inches
Area of triangle
Area of the shade region:
Answer:
77 1/3
Step-by-step explanation:
to get x you have to divide both sides by 36
2784=36x
x=77 1/3
