Answer:
-9 and 3
Step-by-step explanation:
as -9×3= -27
and
-9+3= -6
Given expression:
2x(x + 7)-(3x +1);
To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;
2x(x + 7)-(3x +1)
Distribute 2x over the first parentheses;
the negative sign distributes over the second part
= (2x² + 14x) - 3x -1
= 2x² + 14x -3x -1
Add like terms;
= 2x² + 11x -1
This expression 2x² + 11x -1 is equal to the given one
Answer:
The answers of the proof are the following:
2. Division Property of Equality
3. x+ 1 = -4
4. Subraction Property of Equality
5. x = -5
