4) fifteen less than y is 32
15 - y= 32
15 - (-17)= 32
two negatives become positive so 15+17= 32
12m²n² -8mn +1
[6mn-1]•[ 2mn-1]
[ 6mn•2mn + 6mn•-1 + -1•2mn +-1•-1]
= [ 12 m²n² -6mn -2mn +1]
= [ 12m²n2-8mn+1]

Well to find the area, you simply need to find the formulas! Sadly it specifically depends on the shape alothough that’s what googled for! Just look up the formulas and plug in the legnth width and height maybe even perimeter of base! There you have it!
