Discriminant = square root (b^2 -4*a*c)
square root (64 -4*1*12) =
square root (16) =
4
Therefore it has 2 rational soltions
Answer:

2(−0.45)5=9.2
Step-by-step explanation:
=23.45
Answer:
36.1 meters
Step-by-step explanation:
Since this is a rectangle, the parallel sides are equal to each other, meaning we technically already know all the side lengths.
I'll choose to look at the bottom triangle in this case
30 is already there, and the other leg should be 20. Knowing this, we can plug these into the pythagorean theorem.
20 is A, 30 is B, and the missing side is C

C, the missing side to the nearest tenth is 36.1 meters
Equation for what? Amount after so and so number of years?
If so, then A = $70(1+0.10)^t, where t is the # of years.
