Answer:
Yes, the boats are safe to ride.
Step-by-step explanation:
40 (4) + 12 (2) ≤ 500
160 + 24 ≤ 500
184 ≤ 500
184 is less than 500.
because I was not sure if you had 9 adults instead of 2, this is the answer:
40 (4) + 12 (9) ≤ 500
160 + 108 ≤ 500
268 ≤ 500
268 is less than 500

17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i
19)
x² + 3 = 0
x² = -3
x = ±√-3
x = <span>±</span>√3i
hope this helps, God bless!
Answer:B
Step-by-step explanation:
The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2
Shawna will climb 45 steps
The first step is to write out the parameters given in the question
Shawna climbed 5 flights of stairs
There were 9 steps in each flight
The number of steps can be calculated by multiplying the number of flight of stairs by the number of steps
= 9 × 5
= 45
Hence there are 45 steps for Shawna to climb
