Step-by-step explanation:
let width = w
if width = w, then length = w + 4
Therefore the perimeter is 2w + 2(w+4)
2w + 2(w+4) = 4w + 8
perimeter = 60cm
4w + 8 = 60
<em>-8</em>
4w = 52
<em>divide each side by 4</em>
w = 13
length = w+4
therefore, length = 17
Answer:
(x-4)² + (y+3)² = 9
Step-by-step explanation:
The equation of a circle of radius r centered at (h, k) is ...
... (x-h)² + (y-k)² = r²
Subsituting your given values gives ...
... (x -4)² +(y -(-3))² = 3²
... (x -4)² +(y +3)² = 9
Answer:
Total cost of the car including tax=$4,066
Step-by-step explanation:
Sales tax rate=7%
Price of the car=$3800
Sales tax=7% of 3800
=7/100×3800
=$266
Total cost of the car=price of the car+ sales tax
=$3800+$266
=$4,066
