Answer:
R(-4,-8) and T(-8,8)
Step-by-step explanation:
- Dilation multiplies or divides. Since it is .5 dilation, the pre-image has greater points.
- This multiplying each end point by 2 gives us our pre-image values.
Step-by-step explanation:
Let's call L the length and W the width. The length is 10 feet longer than the width, so:
L = W + 10
The area is the length times width, so:
119 = LW
Substituting:
119 = (W + 10) W
119 = W² + 10W
0 = W² + 10W − 119
0 = (W + 17) (W − 7)
W = -17 or 7
Since W must be positive, W = 7.
L = W + 10
L = 17
The length and width are 17 feet and 7 feet, respectively.
