Answer:
First question: 1.4
Second question: Option 3
Step-by-step explanation:
First question:

-0.4 x -3.5 = 1.4 , -0.4 x 2.9 = -1.16
1.4k - 1.16
For this to equal the right equation, the number missing must be 1.4.
Second question:
You simplify the equation given to you first,
1/4 x 8 = 2 , 1/4 x 12 = 3
2x + 3
The option that is equivalent to the answer is option 3; 2x + 3
