Answer:
ET = 80/A^2
Step-by-step explanation:
First, isolate the variables that you need, which is E and T, using the two equations you were given.
EA = 8
E = 8/A (divide A on both sides to isolate E)
AT = 10
T = 10/A (divide A on both sides to isolate T)
Now, substitute.
ET --> (8/A) x (10/A) = 80/A^2
Answer:
t=-3
Step-by-step explanation:
6t=−18
t=-18/6
t=-3
First try it out yourself then compare answers. Remember, all squares have the same length per each side.
a) 3025
b) 25300
I think it is 10 because 18×10=180 but it is close hope this helps
