Answer:
20m
Step-by-step explanation:
The rooms are 4m x 5m.
To find the area, multiply length by width: 4*5=20
Answer:
Inductive conclusion has been proved to be correct.
Step-by-step explanation:
From the question, we have seen that 3 + 5 = 8
3 and 5 are odd numbers while 8 is an even number.
Which means that the sum of both odd numbers gave and even number.
In the second case, we see that;
13 + 5 = 18
Again,13 and 5 are both odd numbers while 18 is an even number.
Now, Inductive Reasoning is a reasoning that is based on patterns one has observed which would be used to derive a general conclusion. In this question, the pattern observed is that the sum of odd numbers in both cases are equal to an even number.
Thus, we will arrive at a conjecture which is the general conclusion that the sum of 2 odd number is equal to an even number.
15* 60/100=9 liters
15+9=24 liters therefore, the answer is 24 liters

2B + 3C
= 2 ![\left[\begin{array}{ccc}4&-5\\-2&1\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%26-5%5C%5C-2%261%5C%5C%5Cend%7Barray%7D%5Cright%5D)

Multiply each element in the matrices by the scalar quantity, that is
= ![\left[\begin{array}{ccc}8&-10\\-4&2\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D8%26-10%5C%5C-4%262%5C%5C%5Cend%7Barray%7D%5Cright%5D)

Add corresponding elements from each matrix
= ![\left[\begin{array}{ccc}8+3&-10-3\\-4-18&2+9\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D8%2B3%26-10-3%5C%5C-4-18%262%2B9%5C%5C%5Cend%7Barray%7D%5Cright%5D)
= ![\left[\begin{array}{ccc}11&-13\\-22&11\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D11%26-13%5C%5C-22%2611%5C%5C%5Cend%7Barray%7D%5Cright%5D)
