Answer:
bro so big question how can I answer
Explanation:
Which two of the following numbers have a product that is between –1 and 0?
Indicate both of the numbers.
–20
–10
2 –4
3 –2
Explanation
For this question, you must select a pair of answer choices. The product of the pair must be negative, so the possible products are (–20)(2–4), (–20)(3–2), (–10)(2–4), and (–10)(3–2). The product must also be greater than –1. The first product is The fraction with numerator negative 20 and denominator 2 to the power 4, equals the negative fraction with numerator 20 and denominator 16, which is less than negative 1., the second product is The fraction with numerator negative 20 and denominator 2 to the power 3, equals the negative fraction with numerator 20 and denominator 9, which is less than negative 1., and the third product is, The fraction with numerator negative 10 and denominator 2 to the power 4, equals the negative fraction with numerator 10 and denominator 16, which is greater than negative 1., so you can stop there. The correct answer consists of Choices B (–10) and C (2–4).
Which of the following integers are multiples of both 2 and 3?
Indicate all such integers.
8
9
12
18
21
36
Explanation
You can first identify the multiples of 2, which are 8, 12, 18, and 36, and then among the multiples of 2 identify the multiples of 3, which are 12, 18, and 36. Alternatively, if you realize that every number that is a multiple of 2 and 3 is also a multiple of 6, you can identify the choices that are multiples of 6. The correct answer c
