Answer:

Step-by-step explanation:

The median AB bisects DC at right angles ,hence BD = 4

Using Pythagoras' identity on the right triangle ABD

The square on the hypotenuse AD is equal to the sum of the squares on the other 2 sides, that is

AB² + BD² = AD², that is

AB² + 4² = 5²

AB² + 16 = 25 ( subtract 16 from both sides )

AB² = 9 ( take the square root of both sides )

AB = $\sqrt{9\\}$ = 3 feet → A

Trinity solved the equation 2(x-3)+7-3x=11.

lukranit [14]

Answer:

$x=-10$

Step-by-step explanation:

$2(x-3)+7-3x=11$

$2\left(x-3\right)+7-3x-7=11-7$

$2\left(x-3\right)-3x=4$

$-x-6=4$

$-x-6+6=4+6$

$-x=10$

$\cfrac{-x}{-1}=\cfrac{10}{-1}$

$x=-10$

A gardener has 140 feet of fencing to put around a rectangular vegetable garden. The function A(w)= 70w - w^2 gives the garden's

White raven [17]

The largest area that can be enclosed will be that of a square (140 ft)/4 = 35 ft on a side. Such a square has an area of (35 ft)² = 1225 ft², not enough for the garden to be 1300 ft². This tells us the solution to the equation you're being asked to write is non-real.

_____

Putting the given numbers in the area equation, you have

... 1300 = 70w -w²

Multiplying by -1 and completing the square, we have

... w² -70w +35² = -1300 +35²

... (w -35)² = 1225 -1300 = -75

Taking the square root shows us the solution is non-real.

... w - 35 = ±√(-75) = ±5i√3

... w = 35 ± 5i√3 . . . . . . . . . after adding 35. These are complex solutions.
