PLEASE PLEASE PLEASE HELP QUICK AND FAST, YOU DON'T EVEN NEED TO SHOW HOW YOU GOT YOUR ANSWER BUT PLEASE HELP ME FAST I WILL GIVE YOU BRAINLIEST!! Solve for x: 3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1) A) 3 2 B) 2 3 C) − 2 3 D) − 3 2

We need to factor this trinomial by grouping.

The first step in this process consists of splitting the middle term into two terms.

In our example,  has been split into  and .

Notice that one common factor can be factored from the first 2 terms, and another from the second 2 terms

Step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
