Final answer:
Math problems have been solved using multiplication rules. First problem's result is 120X - 360, assuming X is a variable. The second problem's math is correct but equating to 0 is likely a typo.
Step-by-step explanation:
The subject of this question is Mathematics, and it is suited for a High School level student. To solve the multiplication problems provided, we should apply the rules for multiplying numbers with different signs.
Problem 1: (6)(4)(-1)(-5X-3)
We start by multiplying the constants. Since we have two negative numbers (-1)(-5), the result will be positive, following the multiplication rule number 6. Therefore, (-1)(-5) equals 5. Now, let's multiply the rest of the positive numbers: (6)(4)(5) which equals 120. As X is not defined, we simply show the multiplication with X and -3.
Final result for Problem 1: 120X - 360
Problem 2: (6)(4)(-1)(-5)(-3)=0
This problem has a series of multiplications following rules 5, 6, and 7 for multiplication. We will first multiply (6)(4) to get 24, then (-1)(-5) to get 5, and lastly incorporating (-3) to find the overall product. Multiplying these together, we get 24 * 5 * (-3) which is -360. However, since the equation equates to 0, there seems to be a mistake as -360 does not equal 0.
Note: If there is a typo in the provided equation, the right side should not be 0 unless there are other terms or factors that were omitted. Double-checking the problem statement is recommended.
