Given:
The expression is

To find:
The expression which is not a correct way to rewrite the given expression.
Solution:
We have,

Using distributive property, we get


Using distributive property the given expression can rewritten as:

Only the expression in option A is not a correct way to rewrite the given expression because
is not distributed to
properly.
Therefore, the correct option is A.
Answer:
1.x^7
2.x^10
3.a^2
4. 5
Step-by-step explanation:
1. x^(5+2)=x^7
2.x^(5*2)=x^10
3.a^(5-3)=a^2
4. 5 * 1=5
Answer:

Step-by-step explanation:
Given
![A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%266%5C%5C3%265%5Cend%7Barray%7D%5Cright%5D)

Determine the determinant
For a two by two matrix, A such that:
![A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%26b%5C%5Cc%26d%5Cend%7Barray%7D%5Cright%5D)
The determinant |A| is:

So, in
![A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%266%5C%5C3%265%5Cend%7Barray%7D%5Cright%5D)
The determinant is:



There are 9,000 markers in total
750 x 12 = 9,000
We need to work out first the scale factor of the side length
Side MN correspond to the side JK
Side MN = 3.5 cm
Side JK = 14 cm
Scale factor = 14/3.5 = 4
Side OM correspond to side LJ
Side OM = 12 cm
Side LJ = 12 × 4 = 48 cm
