Expand 5-8(-8-3f)
To expand 5-8(-8-3f), we need to distribute the "-8" to both the "-8" and "-3f" terms:
5 - 8(-8 - 3f)
Remember that when multiplying a negative number with a negative number, the result is positive. Also, when multiplying a negative number with a positive number, the result is negative.
So, we have:
5 + 8(8) + 8(3f)
= 5 + 64 + 24f
= 69 + 24f
Therefore, the expanded form of 5-8(-8-3f) is 69 + 24f.
