Answer:
9 + p ≤ 27; p ≤ 18
Step-by-step explanation:
"At or below" means "less than or equal to." Only one answer choice incorporatest that symbol into the inequality expression — the one shown above.
Answer: We should add the constant 81 to the expression to have a perfect square trinomial.
The perfect square trinomial that would be formed would result from (x + 9)^2.
We can use foil to prove it.
(x + 9)(x + 9)
x^2 + 9x + 9x + 81
x^2 + 18x + 81
81 is the value that must go with 18x in the middle to form the perfect square trinomial.
Answer:
7000 cal/min
Step-by-step explanation:
It is mentioned that, Lucia is using energy at a rate of 420 kilo calories per hour ice skating
We know that,
1 kilo calories = 1000 calories
Using unitary method :
420 kilo calories = 420,000 calories
Also,
1 hour = 60 minutes
In this case, Lucia is using energy per 60 minutes = 420,000 calories. So,energy used by her per minute is :
Hence, Lucia is using 7000 calories per minute.
