Answer:
∠ I ≈ 60.3°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan I = 
= 
= 
, thus
∠ I = 
( ) ≈ 60.3° ( to the nearest tenth )
Assuming 5a3 equals 5a^3, and the same for everything else, you would plug in 4 for a, so 5(4)^3 - 2(4)^2 + 4 - 45, which equals 247.
Multiply by -8 on both sides and you will get w=-48
Her check register will have a surplus of 64 dollars compared to her actual balance.
example
100 +32 = 132 (incorrect)
100 -32 = 68 (correct)
132 -68 = 64 surplus
