Answer:
(-6)(-7)= +42
Step-by-step explanation:
(-6)(-7)
a negative multiplied with another negative has always a positivo answer,thus our result is positive
-6×-7= 42
Given:
Consider the expression simplifies to .
To find:
The value of a.
Solution:
We have,
Using distributive property, we get
On comparing the coefficients of from both sides, we get
Therefore, the value of a is 6.
