It’s A because (-2)2+(4)2-2(-2)+4(4)+8=0
-4+8+4+-16+8
(8+8) (-4+4) (-16)
16 -16 =0
Answer:
2x + 6
Step-by-step explanation:
You multiply 2 by the numbers in parentheses. 2 times x is 2x, and 2 times 3 is 6.
Answer: Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted
Step-by-step explanation:
Given: Amelia, Luis, Shauna, and Clarence used different approaches to solve the inequality
7.2b + 6.5 > 4.8b – 8.1.
If Luis started by subtracting 4.8b from both sides ,then he would get
7.2b + 6.5 - 4.8b> 4.8b – 8.1- 4.8b
⇒2.4b + 6.5 > – 8.1. But he wrote 2.4b + 6.5 < – 8.1 by flipping the inequality sign which was not correct .
The sign of inequality get flipped if we multiply or divide a negative numbers to the both sides .
Therefore, Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted.
