Answer:
LM=11
Step-by-step explanation:
LN= ML+MN
4x+9=(2x+7)+(3x)
4x+9=5x+7
5x-4x= 9-7
x=2
LM=2x+7 =2(2)+7=4+7=11
The last one, as the the scale factor is 3. If we divide each side of the first triangle by their corresponding sides, such as (21/7, or 6/2), we get the same result, which is 3. All others are wrong because in the first one we are not giving all sides, and the second one doesn’t have the same scale factor for its sides. Hope this helps.
Answer:
The inverse matrix is used to solve the system of linear equations. It also tells us the consistent or inconsistent behaviour of the solution of equations.
Step-by-step explanation:
In real life,
- Whereas in programming which is taught at the university, matrices and inverse matrices are used for coding and encrypting messages.
- Matrices are also used in representing the real world data's like the population of people, infant mortality rate, etc.
- They are best representation methods for plotting surveys.
we know that
the speed's formula is equal to
in this problem we have
Substitute the values in the formula
therefore
<u>the answer is</u>
