Write matrix to represent system 2a-3b=6,a=b=2

The matrix that represent the system 2a-3b=6,a=b=2. The given system of equation is a bit vague due to a=b=2. So the matrix that will represent is:

|2  -3  6|

|     1   2|

But if the equal sign is either a plus or a minus, the matrix will change to:

|2    -3      6|

|1  +/- 1   2|

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
