Ineed an explanation to this and an answer

fill in the missing pieces of the problem using distributive property. you will need to get an answer of 48.

4 ( __ +

answer = 48

There are infinitely many answers to this question.

Step-by-step explanation:

This question can be written as  4 ( __ + __)  = 48

Simplifying gives us

( __ + __)  = 12, so any summation of 2 numbers that equals 12 will solve this.

There are infinitely many since you will use PEMDAS to simplify what is in the parethesis before multiplying by 4.  

Some examples are

1 and 11

0 and 12

-48 and 60

0.5 and 11.5

192 and -180

...as you can see, there can be infinitely many numbers combinations written to satisfy this equation.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

the second option
