Step-by-step explanation:
-5 (-6k + 10)
= 30k - 50
522 − 482 = (52 + 48)(52 − 48) = (100)(4) = 400
522 − 482 = 2704 − 2304 = 400
522 − 482 = (52 − 48)2 = (4)2 = 16
The optionsecond 52² − 48² = (52 + 48)(52 − 48) = (100)(4) = 400 is the correct.
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We know,
a² - b² = (a + b)(a - b)
We have:
= 52² − 48²
After using the above identity, we get:
= (52 + 48)(52 - 48)
= (100)(4)
= 400
Thus, the optionsecond 52² − 48² = (52 + 48)(52 − 48) = (100)(4) = 400 is the correct.

Answer:
A. convenience sampling
Step-by-step explanation:
The sampling procedure used by Steven is convenience sampling.
Convenience sampling is a sampling method, where samples are drawn from the closest samples available.
For example: A teacher surveying for something chooses samples from her own class. The students of her own class are the closest available samples.
