Here, we want to get what Andre's mistake was and correct it
To answer this, we are supposed to use the division law of indices
We have this as;
Now, in the case of this question, x is 4 and y is -3
So, we have the expression as;
His mistake is thus adding the exponents instead of subtracting
Answer:
Step-by-step explanation:
surface of the entire object
1) bottom. 8*16= 128 sq inchs
2) triangle sides. 1/2 b*h = 1/2*16 *6 = 48 but there are 2 , the front, and the back. (2*48)=96 sq
3) pitched tops 10*8=80 but there are 2 80*2 = 160 sq
total = 1+2+3
total = 128 + 96 + 160
total surface area = 384
