Question

a factor is a number that divides into another number evenly, with no remainder. select two answers that are two different factors of -60 3 and 20 -3 and 20 4 and -15 -4 and -15

Explanation:

To determine if two numbers are factors of \(-60\), we check if their product is \(-60\) (since if \(a\) and \(b\) are factors of \(n\), then \(a\times b = n\)).

Step 1: Check "3 and 20"

Calculate the product: \(3\times20 = 60
eq - 60\). So, 3 and 20 are not factors of \(-60\).

Step 2: Check "-3 and 20"

Calculate the product: \(-3\times20=-60\). So, - 3 and 20 are factors of \(-60\).

Step 3: Check "4 and -15"

Calculate the product: \(4\times(-15)=-60\). So, 4 and - 15 are factors of \(-60\).

Step 4: Check "-4 and -15"

Calculate the product: \((-4)\times(-15) = 60
eq-60\). So, - 4 and - 15 are not factors of \(-60\).

Answer:

B. -3 and 20, C. 4 and -15
