D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.
4/8=x/6. Then just cross multiply and solve from there.
Is that negative 2 minus 8? if so put that into the calculator and add 8 to both sides and divide by 2 after that. simple algebra
Assuming you meant 45x^2y^2+18*3 , it should be 9(5x^2y^2+6)
Answer:
x=9
Step-by-step explanation:
9+3=12
12/2=6
In general, any equation like
(assuming
) is solved by

So, in your case, the solution is

Dividing by a fraction means to multiply by the inverse of that fraction:
