The area of a rectangle is 54 feet^2 The length of the rectangle is 3 feet more than twice the width find the dimensions of the rectangle

Width: 9/2

Length: 12

Step-by-step explanation:

x = the width of the rectangle, so 2x+3 = the length of the rectangle. To solve for the dimensions, the equation for the area is x(2x+3) = 54. Expand to get 2x^2+3x = 54. 2x^2+3x-54 = 0, factor to get (2x-9)+(x+6) = 0. x = (9/2), or -6. Since the width of a rectangle can't be negative, x = (9/2). 2*(9/2)+3 = 9+3 = 12. Hope this helps! :)

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
