Answer:
x=-26
Step-by-step explanation:
Subtract 45 from both sides.
-85-45=5x
Simplify -85-45 to -130
-130=5x
Divide both sides by 5.
-130/5=x
Simplify 130/5 to 26
-26=x

Answer: A and C</h3>
Both matrices are 1 x 4 matrices. This notation says there is 1 row and 4 columns. The number of rows must match up, as well as the number of columns, in order for matrix addition to be possible. This is so the corresponding elements pair up and add together. For instance, the 5 and -2 pair up and add together for matrices A and C.
8^2 = 8*8 = 64
3^3 = 3*3*3 = 27
2^4 = 2*2*2*2= 16
10^5 = 10*10*10*10*10 = 100000
