X-10 = 0 results in x = 10, and x + 8 = 0 results in x = -8.
The two solutions are x = 10 and x = -8
44x + 55x + 77x = 6,464 centimeters.
x =

OR maybe that's another of those infamous Brainly typos.
4x + 5x + 7x = 64 centimeters.
x = 8
Therefore the sides are
4*8 = 32
5*8 = 40 and
7*8 = 56 centimeters
Answer:
x=9
y=2
z=1
Step-by-step explanation:
xx+yy=zyz
xx can be divided by 11
yy can be divided by 11
zyz can be divided by 11
3 digit multiples of 11
110
121
132...
121=zyz because z=1 and y=2
121-22=99
xx=99
x=9
z=1
y=2
