Expanded form of 3( 6 + 7) is
Need to use distributive property to write the expanded form of 3(6 + 7)
Let’s understand what is distributive property.
The distributive property states that multiplying a sum by a number gives the same result as multiplying each addend by the number and then adding the products together.
According to distributive property, for numbers a , b and c
----- eqn 1
3(6 + 7) can be rewritten as 3 ( 6 + 4 + 3 ) = 3 ( 10 + 3 )
Now in our case a = 3 , b = 10 and c = 3
On substituting the values of a , b and c in equation 1 we get
So expanded form of 3( 6 + 7) is
Answer:
The equation of the tangent line is .
Step-by-step explanation:
Firstly, we obtain the equation for the slope of the tangent line by implicit differentiation:
(1)
If we know that , then the slope of the tangent line is:
By definition of tangent line, we determine the intercept of the line ():
(2)
If we know that and
, then the intercept of the tangent line is:
The equation of the tangent line is .
