Answer:
Start by laying out 7 tiles, and then adding 3. Whatever that number of tiles is equals x.
x = 10
10 - 3 = 7
Answer:
x=4
Step-by-step explanation:
log(2x-7) = 0
10^[log(2x-7)] = 10^0
2x-7 = 1
2x = 8
x = 4
Recall that the characteristic polynomial of a 2x2 matrix

is

but

and

, so the characteristic polynomial for

is

We're given that the trace is 15 and determinant is 50, so the characteristic polynomial for the matrix in question is

and the eigenvalues are those

for which the characteristic polynomial evaluates to 0.
