The answer is 10x^2y + 23xy - 5
9(10)=90
8(9)=72
7(8)=56
6(7)=42
5(6)=30
4(5)=20
3(4)=12
3=12
The last one is the answer h=2t-d distribute the 1/2 into the (d + h) you get t=1/2d + 1/2 h then multiply everything by the denominator of 2 this would give you 2t = d + h because the denominator of 2 on the d and h cancel out and leaves a 1 infront which is just d and h then i’d u switched the h and 2t across the equation they become the opposite sign -h = -2t + d since you don’t want -h switch all the signs leaving you with the answer h = 2t - d
