FOR YOU CAN ANSWER THESE TWO

First question: 1.4

Second question: Option 3

Step-by-step explanation:

First question:

You simplify the left equation first,

-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

the discriminant is 64 + 4*1*12 = 112

this is prime.
