false
question 10 (1 point)
6×2 + 4 - 10 = 6
true
false
question 11 (1 point)
11 + 2 - 3×5 = 0
true
false
question 12 (1 point)
5×(4 - 2)+6
a 16
b 0
c 12
d 44

Explanation:

Step1: Solve Question 9

First, perform multiplication: $3\times5 = 15$. Then, calculate $20 - 15+9=5 + 9=14$.

Step2: Solve Question 10

Perform multiplication first: $6\times2=12$. Then, calculate $12 + 4-10=16 - 10 = 6$.

Step3: Solve Question 11

Perform multiplication first: $3\times5 = 15$. Then, calculate $11+2-15=13 - 15=-2
eq0$.

Step4: Solve Question 12

First, solve the parentheses: $4 - 2=2$. Then, perform multiplication: $5\times2 = 10$. Finally, $10+6 = 16$.

Answer:

Question 9: True
Question 10: True
Question 11: False
Question 12: a. 16
