(a-1)²(b-1)²=a²b²+a²-b²+1²=(ab)²+(a-b)²+ 1
Answer:
I think it might be the third one or the last one
Answer:

Step-by-step explanation:
First, we open the parentheses by multiplying the contents of the parentheses by 3 (because it says 3(2x+6)). The final result is <u>6x+18</u>
The solution 92 is how tall the basil plant becomes in two weeks after he starts recording its height.
There's 14 days in two weeks.
There's no equation shown, but I suppose it was like this:
5x+22=92
But once you insert 14 days in the equation, it'll become:
5(14)+22=92
70+22=92
92=92
