Answer: The answer is 12 cm and 32 cm.
Step-by-step explanation: Let, 'x' cm be the breadth of the rectangle, then according to the question, the length will be (x + 20) cm.
Also, given that if the smaller side is made two times larger and the larger side three times larger, then the perimeter of the new rectangle would be 240 cm. So, we have
So, the width of the original rectangle is 12 cm and its length will be (12 + 20) cm = 32 cm.
Thus, the lengths of the sides of original rectangle are 12 cm and 32 cm.

Step-by-step explanation:
There are two points where y = -3
at x = -2 and x = 1
when x = 0 f(0) = 1
Answer:
w= -9/8
Step-by-step explanation:
-1/3w -3/5 = 1/5w
+1/3w +1/3 w
-3/5=1/5w+1/3w
Make common denominators to combine like terms of the right
-3/5=1/5w+1/3w
*3 *5
-3/5=3/15w+5/15w
-3/5=8/15w
multiply both sides by the reciprocal of 8/15 which is 15/8
-3/5*15/8=8/15w*15/8
* ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3
* -----> now multiply across
w= -9/8
Plug in 4 for r and 1 for s
r+s^2
4+1^2
Evaluate exponents first (order of operations)
4+1
Add
5
Final answer: 5
