The width of rectangle is 6.

Step-by-step explanation:

Given,

Area of rectangle; w²+4w=60

As w is the width, we will solve the equation to find w.

w^2+4w=60

Subtracting 60 from both sides

w^2+4w-60=0

Factorizing the equation;

w^2+10w-6w-60=0\\w(w+10)-6(w+10)=0\\(w+10)(w-6)=0

Either,

w+10=0         => w=-10

Or,

w-6=0           =>w=6

As width cannot be negative, therefore

Width = 6

The width of rectangle is 6.

If the domain of the coordinate transformation (, ) = ( + 2,− − 4) is (1, -4), (3, -2), (0, −1), what is the range?
timama [110]

Answer:

A. (-2, -5), (0, -7), (1, -4)

Step-by-step explanation:

The following transformation is applied:

(x,y) \rightarrow (y + 2, -x - 4)

To find the range:

We apply the transformation to the points in the domain. Thus:

(1,-4) \rightarrow (-4 + 2, -1 - 4) = (-2, -5)

(3,-2) \rightarrow (-2 + 2, -3 - 4) = (0, -7)

(0,-1) \rightarrow (-1 + 2, 0 - 4) = (1, -4)

Thus the correct answer is given by option a.
