Solve 4/5x-9=3 I REALLY NEED THIS ASAP

Mathematics
2 answers:
Olin [163]4 years ago
7 0

I will assume that you meant (4/5)x - 9 = 3.  In other words, (4/5) is the coefficient of x.

Start by adding 9 to both sides:  (4/5)x - 9 + 9 = 3 + 9, or (4/5)x = 12.

To isolate x, mult. both sides by (5/4):                         (5/4)(4/5)x = (5/4)(12)

Simplifying this result, x = 15

6. Let A and B be nxn matrices . Compute (A + B) (A + B). Explain all steps.
Pie

Answer:

(A+B)(A+B)=A.A+B.A+A.B+B.B

Step-by-step explanation:

Given that matrices A and B are nxn matrices

We need to find (A+B)(A+B)

For understanding the multiplication of matrices let'take A is mxn and B is pxq matrices,we can multiple only when n=p,so our Ab matrices will be mxq.

We know that that in matrices AB is not equal to BA.

Now find  

(A+B)(A+B)=A.A+B.A+A.B+B.B

So from we can say that (A+B)(A+B) is not equal to A.A+2B.A+B.B because AB is not equal to BA in matrices.

So (A+B)(A+B)=A.A+B.A+A.B+B.B
