Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Distributive law is defined as

According to option'A', we get that
a =- 3
b = 6
c = 0.4
d = 0.08
So, it becomes,

Hence, option 'A' is correct.
Answer:
D. 14°
Step-by-step explanation:
The Law of Sines tells you sides are in proportion to the sine of the opposite angle:
sin(A)/BC = sin(B)/AC
sin(A) = BC/AC·sin(B)
A = arcsin(BC/AC·sin(B)) = arcsin(7/28·sin(75°)) ≈ 13.974° ≈ 14°
Answer:
D is correct. ( 4m - 5 ) + ( -6m + 7 - 2n )
Step-by-step explanation:
We are given a difference of two polynomial
(4m-5) - (6m-7+2n)
We need to choose correct choice which is equivalent to given expression.
Here we have minus sign between two parentheses.
First we distribute minus sign over (6m-7+2n) using distributive property.
Minus sign will distribute with each term inside (6m-7+2n).
When it will distribute it changes the sign of each term inside the parentheses.



After distribution we get
( 4m - 5 ) + ( -6m + 7 - 2n )
Thus, D is correct option which is similar to given expression.
