The perpendicular line through (2, 1) is
.. y = (x -2)+1
or
.. y = x -1
Answer:
Step-by-step explanation:
x+41=-90 (original problem)
-41 -41 (you must get rid of the common factors by doing the opposite on both sides)
x= -132 (add -90 and -41 to get -132)
Answer:
48 cm²
Explanation:
Let the breadth be b, then the length is 3b
P = 2(Length + Breadth)
32 = 2(3b + b)
32 = 2(4b)
8b = 32
b = 4
Breadth is 4 cm
Length: 3b = 3(4) = 12 cm
Area of rectangle:
Length × Breadth
12 × 4
48 cm²
