Y²(9y² + 4y - 9)
Simplify.
(y² · 9y²) + (y² · 4y) + (y² · -9)
Simplify.
9y⁴ + 4y³ - 9y²

False because parentheses go first.... just follow PEMDAS
At sea level, the pressure is 1013, that's when the altitude is at 0, sea level, let's see
so, the inital amount is 1013, when t = 0,
now, to check the atmospheric pressure at 4000, simply set t = 4000, to get A.
Distance = rate times time. Thus,
d = (68 mph) (5.25 hrs) = 357 miles (answer)
Answer:
Step-by-step explanation:
Mathematically, if two triangles are similar, then all the three of their angles are congruent to each other and their corresponding sides are in the same proportion. This means that the ratio of their corresponding sides are equal to each other.
