Answer:
perimeter = sum of all sides. this is same for polygons
rect: area l×b. peri = 2(l+b)
Step-by-step explanation:
15+5 = 20
20*2 = 40 cm is the perimeter of the given figure
Answer:
Lol have fun
Step-by-step explanation:
Let x = the shorter piece and Let y = the longer piece.
(3/4)x = 120
x = 120 / (3/4)
x = 120 * (4/3 = 480/3) = 160 feet
y = 160 + 12
Well.. You seem to have forgotten to add the coordinates...
Anyway, the line is represented by the function f(x) = 3x .
Any point which follows the form (x,3x) will be on the line
for example (-3,-9) ; (-2,-6) ; (-1,-3) ; (0,0) ; (0.333333,1) ; (1, 3) ; (2,6) ; (3,9) ; and so on....
Answer:
x = 71
Step-by-step explanation:
The sum of the angles in a triangle is 180
x +82+27 =180
Combine like terms
x +109 = 180
Subtract 109 from each side
x+109-109 = 180-109
x = 71
