Answer:
The correct option is A.
Step-by-step explanation:
The given expression is
If a ,b, c are three real number, then by distributive property,
Using distributive property, then given expression can be written as
Option A is not a correct way to rewrite the given expression and option C represents a correct way to rewrite the given expression.
Using distributive property, then given expression can be written as
Option D represents a correct way to rewrite the given expression.
Again using distributive property in the above expression, we get
Option B represents a correct way to rewrite the given expression.
Therefore the correct option is A.

Answer:
a = 8; b = -9
Step-by-step explanation:
Filling in the given values gives you two equations.
7 = a(2) +b
-1 = a(1) +b
Subtracting the second equation from the first gives ...
(7) -(-1) = (2a +b) -(a +b)
8 = a . . . . . simplify
Using this value in the first equation gives ...
7 = (8)(2) +b
b = 7 -16 = -9
The constants are a = 8, b = -9.
Answer: The area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.
Step-by-step explanation:
I will assume that the exercise says " times the base and height of Jerry’s rhombus".
The area of a rhombus can be calculated with the following formula:
Where "b" is the length of the base and "a" is the altitude or the height.
Then, you can calculate the area using the formula shown above.
Therefore, you get:
1. Jerry's rhombus:
2. Charlene's rhombus:
Dividing the area calculated, you get:
Therefore, you can conclude that the area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.
