Answer:

0.4

Step-by-step explanation:

consider this like some lines overlapping each other.

one line (A) is 0.5 long, the other (B) 0.4 long.

together they are 0.8 long.

that means that they overlap at a length of 0.1 (they share a segment 0.1 long).

of the combined line of 0.8 that has 0.1 of a joined segment, the complimentary part of B is therefore 0.4 (0.8 minus the original length of B).

Helppppppp pleaseeeeee
Dahasolnce [82]

Step-by-step explanation:

The area, A, in square yards, of a rectangular garden, is given by the function.

A(x)=-2x^2+30x

We know that, the area of the rectangle is given by :

A=l\times b

Where l is length and b is breadth

A=-2x^2+30x\\\\A=2x\times (-x+15)

Length = 2x

Breadth = (15-x)

For zeoes,

2x\times (-x+15)=0\\\\x=15

Length = 15 yards

Breadth = (15-15) = 0 yards

Hence, this is the required solution.
