Arectangular flower bed is enlarged so that its area increases by 24 ft². the enlarged flower bed is a rectangle and its area is x2+11x+24 ft².
which expressions represent the dimensions of the flower bed before the increase?

The dimensions of the flower bed before the increase are x ft by (x+11) ft

Step-by-step explanation:

Let

A -----> the area of the flower bed before the increase

B -----> the area of the enlarged flower bed

we know that

-----> equation A

we have that

-----> equation B

substitute equation B in equation A

Solve for A

Factor x

 ---> area of the flower bed before the increase

Remember that the area of a rectangle is equal to multiply the length by the width

so

therefore

The dimensions of the flower bed before the increase are x ft by (x+11) ft

current in the circuit at time t is /, then the power delivered to the resistor is
